Calculate the total construction volume. How to calculate the volume of a room in m3 calculator

If earlier the choice of what the house would be like was small - from wood or ashlar, today there are plenty of materials, and an accurate calculation of what and how much is needed is required, that’s why it’s needed construction calculator.

In what cases and how is a construction calculator used?

Even if you have not yet decided what materials the house will be built from (and there are plenty of options: brick, silicate or aerated concrete blocks, logs, timber or boards on a frame), the principle will be similar. First, the foundation is made, then the basement, in the process the basement and possibly the basement are formed, then the walls grow, the floors are laid, the rafter system is built and the roof is laid. Everything is simple and, at the same time, very complicated when you consider how many different building materials need to be purchased, transported and placed on the site. And if something is missing, should I go again, look and buy?

So that there are no incidents with a lack of bricks or boards, an online construction calculator is used, that is, a special service on the Internet that allows you to make calculations in a matter of minutes.

The foundation is calculated quite simply, you just need to determine the volume of the future fill, decide in what proportions you will mix the solution, and then calculate the construction of the house. Let's say you want a strip foundation for a small cottage 6x5 meters, divided into 2 rooms, the width of the base will be the same as that of the walls, for example, 40 centimeters, the depth is half a meter. It is not difficult to calculate the volume of fill, multiply 40x50 and get the cross-sectional area, then multiply by the length of the walls (2 x 6 meters and 3 x 5 meters). Since we count in meters, it comes out to 0.4. 0.5. 27 = 5.4 cubes of solution. This will help you on how to calculate the amount of materials.

Calculation of construction of a house with brick and block walls

Not everyone likes a log house, and many find the brick option more practical, especially since well-made masonry has fairly high thermal insulation properties. Typically, walls are built with one and a half bricks, sometimes two; there are other types of masonry, for example, two walls with a void between them filled with bulk material that plays the role of insulation. Building blocks are purchased by the cubic meter, and it is advisable to know exactly how many stacks will be needed for the job. It’s even better to decide in advance on the number of bricks. How? Calculating the construction of a house in this case will be very simple.

Previously, we looked at strip foundations, but why are walls worse, the thickness of which also allows us to calculate their volume? We proceed in the same way, not paying attention to the error arising from the masonry joints (it is better to make them thin so that cold bridges do not arise). Knowing how to calculate the volume of a house, we can easily find out how many cubic meters of brick will be needed. It remains to determine the volume of one piece, divide the first number obtained by the second, and we will find out the required number of bricks. As for expanded clay concrete blocks, since they are exactly 7 times larger in size, there will be just as many fewer of them.

Calculation of frame-type building structures

The greatest difficulty for calculations is presented by frame houses that are now becoming fashionable. The fact is that such structures are quite complex, and only a designer can say in advance how much timber will go into the frame, which will later be sheathed with boards. But it is still possible to calculate a frame house, since the construction of this structure is subject to certain rules. The basis of everything is the lower belt, in the form of a frame made of timber with crossbars, which will become the ceiling of the first floor in the future. Next, corner posts are installed, the cross-section of which depends on how many levels the building is supposed to have. For a two-story house, it is advisable to install the supports from 150x150 millimeter timber.

The number of linear meters of material required for the bottom trim is calculated using the formula: (a+b) . 2, Where a And b– lengths of the sides of the house. The result will be, in fact, the perimeter P the buildings. Let's add crossbars here that will correspond to the shorter wall, let's say it will be a, then the formula will change to this option: P = ((a+b) . 2) +n. Here n– number of crossbars laid in increments j, this value is calculated using the formula: n=b/j – 1, one must be subtracted because the last cross member is already taken into account in the previous formula, being one of a-sides The height of the lower belt is two beams, based on this, taking into account the above formulas, it is possible to calculate the construction of a house from lumber.

Then a power frame is built, consisting of vertically installed supports, the spacing between which is half that of the base crossbars. In other words, their number can be derived from the previously given formula by slightly changing it: n = ((a+b) . 2)/(j. 0.5) – 4, the last number corresponds to the number of corner posts. Where doors and windows will be located, the supports are skipped, therefore, the formula must include subtracting the number of such planned openings. The windows are delimited by two cross beams, the doors by one at the top, in addition to the horizontal beams that top the load-bearing frame of the first floor. For the second floor, the calculation of building structures is done in a similar way, but we will not talk about the rafter system here, it requires separate calculations.

How much does it cost to build a house - the calculator will give you the answer

In general, the pitch, both for the jumpers of the lower chord and for the racks, is selected based on the dimensions of the cladding materials. For example, if the length of the exterior finishing board is 1 meter, and the thickness of the support beams is 15 centimeters, then the step between them should be 85 centimeters so that the elements of the nailed sheathing are joined exactly in the middle of the racks. You should also take into account the standard sizes of the internal cladding, in particular, plasterboard sheets have a width of 60, 80 and 120 centimeters, and it is reasonable to adjust the pitch of the beams to these indicators.

Today, the construction of houses made of foam concrete is gaining momentum. And this is not surprising, because this material has such parameters that cannot but attract buyers. There are several opinions on how to correctly calculate the cost of building a house made of foam blocks.

We will focus on this issue in this article.

Why foam block

First of all, let us remind you: do not confuse foam concrete with aerated concrete. One of the articles on our website discusses in detail the fundamental differences between these two materials. It is worth noting that the price of foam concrete is more favorable.

What he really is

A foam block is a small “block” made by mixing a concrete mixture with special foaming components. It is the foam that forms cavities in the concrete, which reduce its weight and increase its thermal insulation parameters.

Its standard size is 200*300*600 mm. For clarity, look at the photo below and imagine how much time you can save on laying foam blocks.

Houses made of this material cost significantly less than houses of the same size made of brick or, for example, timber. And if you are not lazy and build everything yourself, then the savings will exceed even your wildest expectations.

Having an attractive price, foam block houses or cottages are in no way inferior in their parameters to stone or wooden ones. Another attractive feature of the material is its environmental friendliness.

Advantages of the material

1. No additives that negatively affect human health are used in production, which makes it possible to build children’s or health complexes from it. With such a construction, considerable attention is paid to sound insulation - and foam concrete has no equal in this regard.
2. The structure of the material itself is favorable for further processing. With the help of simple tools you can give the block any desired shape.
3. The porous structure does not interfere with gas exchange and the house “breathes” no worse than a wooden one.
4. From the previous point it logically follows that such a house is not characterized by excessive humidity and dampness. With foam concrete you will forget about mold and drips.
5. Not only the size, but also the principle of laying will help save time and mortar. After all, the gap between the blocks should not exceed 3 mm.
6. Both exterior and interior decoration will also not cause you unnecessary trouble, because the layer of plaster does not have to be thick.
7. Foam concrete has excellent fire resistance. At high temperatures, the material does not crumble or crack and protects the reinforcement from heating. In the event of force majeure, such a house will not let you down.

Disadvantages of the material

There are few of them, but they are still present:

• Low weight with a large volume, of course, leads to a loss of strength. For this reason, foam block has not received and will not receive widespread use in multi-story construction. Although, after all, you are building a private house, and this is unlikely to be a problem, because cottages are rarely higher than 3 floors.
• The need to monitor the correctness of the masonry. If the solution layer exceeds 3-4 mm, then you risk losing both heat and sound insulating properties.

Let's move on to the main question

So, our main task is to calculate the cost of building a house from foam blocks. It cannot be done separately from clarifying the stages of construction. After all, only by analyzing the entire process in parts can you take into account every detail.

Count

The calculation of foam blocks for building a house should be based on the area of ​​the walls. Foam blocks are sold in cubic meters and to find out the quantity you need, simply multiply the thickness of the block by the area of ​​the walls.

Related articles:

The full cost calculation for building a house made of foam blocks is as follows:

• Let us immediately stipulate that our sample has a width of 8 m, a length of 10 m and a height of 3 m. Main and external walls are taken into account.
• the cost of the roof, foundation and other work can be calculated using separate calculators on our website.
• So, let’s calculate the perimeter of the building: 10*2+7.4*2=34.8 m (rounded to 35). A reasonable question arises: how much is 7.4 meters and not 8? The answer is simple: you stacked 2 walls of 10 meters each, and from eight you need to subtract the width of the block, that is, 30 cm.
• Now we find out the area of ​​the walls: 35*3=105 sq.m. Everything is clear here: perimeter multiplied by height.
• From the resulting area, subtract the area of ​​windows and doors. This is purely individual for each project, so for convenience, let’s assume that they occupy 10 sq.m. 95 sq.m. left.
• We find out the area of ​​the foam block: 0.6*0.2=0.12 sq.m. It turns out that for 1 sq.m. accounts for 1/0.12 = 8.3 foam blocks.
• So, we complete the calculation: 95 * 8.3 = 788.5 blocks are needed for the external walls.
• It would seem that the calculation of materials for building a house made of foam blocks is complete, but no! We did not take into account the main wall.
• Its length in our sample will be 9.4 meters. Multiply by height - we get an area of ​​28.2 square meters. Again, let’s assume that the windows and doors will take up 5 square meters. We get 23.2 sq.m. 23.2*8.3= 192.5 blocks.
• We add up the resulting numbers: 788.5+192.5=981 blocks are needed for such a construction.

So, calculations for building a house from foam blocks showed that we need 981 blocks. There are 27.7 blocks in one cubic meter. With a simple calculation we find out that we need 35 cubic meters.

The cost of 1 cubic meter is about 3,000 rubles. As you can see, a house of a given size will cost a very modest amount. Of course, this is just the frame of the building, but you must admit that the same brick would cost 2-3 times more.

It is worth noting that these instructions are approximate and accurate calculations are only possible with a thorough knowledge of the project.

Construction progress

• First of all, the foundation for the house is built from foam blocks. Since the foam block is lightweight, there is no need to spend money on an expensive monolithic foundation. An excellent replacement for it can be a belt one, which uses much less crushed stone, sand, concrete, and even uses reinforcement of a smaller diameter.

• After the base has gained the required strength, it is time for laying. It starts with laying roofing felt between the base and the first row as waterproofing.
• The corner blocks are laid first. Moreover, special attention is paid to the corner, which according to the plan will be the highest. The corner is leveled and proceed to the next one.
• then a cord is pulled over the corners and the space between them is filled. If a whole block does not fit in one of the rows, then the excess part is cut off and the resulting piece is placed in the gap.
• Each next row is installed according to the same principle: from the corners. Verticals and horizontals are checked by level and cord.

Advice!
Remove possible unevenness immediately with a plane.

• To prevent the walls from cracking during shrinkage, the masonry must be reinforced. Reinforcement with a diameter of 8 mm is placed in pre-cut grooves measuring 4 by 4 cm, which after installation are filled with glue or mortar.

• Electrical wiring is also laid in grooves according to the same principle, but the laying pattern depends on the specific project.

• Particular attention is paid to door and window openings. All cut grooves are lined flush with a metal corner.

Another little tip: to cut the blocks you need to use a special hacksaw for foam concrete with large teeth.
If you cut correctly, you will avoid crumbling of the material.

• For interior decoration, drywall, boards and textured plaster are excellent options. It’s even easier on the outside - use siding or finishing bricks.

Let's sum it up

As you can see, calculating the construction of a house made of foam blocks cannot be called a very complicated process. But this in no way detracts from its importance when planning work.

Building a house is a responsible and complex process, the nuances of which are known only to professionals. But the cost of building a house is primarily influenced by the amount of building materials used and the size of the building, so it is possible to roughly estimate the cost of construction for the selected project using online calculators.

Using a calculator and a house project, you can imagine its approximate cost

Types of house construction calculations

There are several types of calculations, and a specific construction calculator is usually created for one of them. To understand what results to expect from the calculations, you need to understand what type of calculations are used:

By total area of ​​the house. A very approximate method of calculation - you indicate the linear dimensions of the building, the estimated number of floors and material for the walls, and the calculator gives an estimated cost.

By project type. A more complex method of calculations, which is carried out in several stages - based on architectural, structural and engineering projects. The cost of building the “box”, finishing work and the cost of laying out utilities are shown separately here. The accuracy of the calculations depends on the number of templates included in the calculator.

Foundation calculators. Allows you to roughly imagine the amount of building materials (concrete, reinforcement, boards for formwork) that will be required for the work. The accuracy of the calculations also depends on the number of templates included in the calculator.

Interface of the online foundation calculator

Universal calculators that allow you to include in the calculations the types of floors and the material from which they are made (blocks, bricks, wooden beams, or even). In some cases, you can even consider houses designed using half-timbered technology.

Depending on the templates and formulas included in the construction calculator, as a result you receive a calculation of the cost of building a house as a whole, or part of the work, so that you can choose the best option.

In what cases and how is a construction calculator used?

To properly use an online construction calculator, you need to clearly understand its pros and cons. At the same time, first of all you have to focus on the shortcomings:

Lack of flexibility. Any calculator makes calculations solely based on its built-in templates and formulas. If you need to calculate data for which the calculator is not provided, then you won’t be able to reconfigure it and you will have to do everything manually.

Low transparency of calculations. Even if the calculator contains exact formulas, the user has no way to check what exactly and how correctly he thinks, since everything is hidden behind the user interface intended exclusively for entering primary data.

Behind the user interface, the formulas by which the calculations are performed are not visible - only the initial data and the result

Despite such significant disadvantages, various construction calculators are still very popular - this is due to the following positive aspects:

Based on the initial data that the calculator requires, you can still imagine the progress of the calculations and what to look for when choosing a project or communicating with the specialists who will perform the work.

Based on the results generated by the calculator, you can compare the cost of work with different materials or compare the price of houses built using different technologies.

As a result, the main task of a construction calculator is to clearly show the user how approximate calculations are made and what the difference is in the cost of houses built using different technologies.

At the same time, it is not recommended to use a building materials calculator for building a house for any precise calculations, since it is often unknown what formulas and with what tolerances the calculations are made.

What do construction calculators calculate?

In order to carry out the most correct calculation of the main building materials for the construction of a building, it is necessary to decide in advance on the design of the house that will be built. When the configuration of the future cottage is known, this data can be used in an online calculator to calculate the amount of materials needed.

An example of a finished wooden house project

Calculation of materials for the foundation

The foundation accounts for approximately a third of all construction costs. Laying out the foundation is one of the first stages of work and calculations usually begin with it. To calculate the amount of building materials, it is proposed to select or manually set the following data:

type of foundation - strip or pile-grillage (it is impossible to calculate a completely pile foundation online, since too many variables must be taken into account);

foundation shape – usually rectangular or with additional load-bearing walls;

linear dimensions - depending on the accuracy of the calculator;

solution proportions - concrete grade;

thickness, and in some cases, the desired length of the formwork boards;

type of reinforcement.

After calculations, the calculator displays the volume of future pouring, the amount of reinforcement and wire for tying, and the cubic capacity of boards for formwork

The nuances of the calculation that arise can be clearly seen in the example of calculating the amount of mortar for pouring a strip foundation measuring 5x6 m for a small country house with two rooms.

A strip foundation is a concrete foundation laid along the perimeter of the house frame under all its load-bearing walls and transferring the load from the cottage to the ground.

Strip foundation

On our website you can find contacts of construction companies that offer. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

When calculating the volume of fill, the width of the base (for example, 40 cm) is multiplied by its depth (50 cm). The resulting cross-sectional area is multiplied by the length of the walls (3 x 5 m and 2 x 6 m).

The simplest calculation could look like this: 0.4x0.5x((6x2)+5x3)) = 0.4x0.5x27 = 5.4 cubic meters. m of solution.

But there is one nuance here that must be taken into account - when the 6 m sides are filled with concrete, then part of the 5 m wall volume is also “captured”. If you do not pay attention to this point, you can order more concrete than necessary. In fact, the calculation will be 0.4x0.5x((6x2)+(4.2x3)) = 0.4x0.5x24.6 = 4.92 cubic meters. m of solution.

Correct calculation of the volume of a strip foundation

As you can see, even on a small foundation the difference is noticeable - a mistake of half a cube of solution, and that’s 1.5-2 thousand rubles...

Nuances of calculating the consumption of bricks and blocks for walls

Since bricks and building blocks have a rectangular shape, the calculation of building a house is carried out with approximately the same initial data, so most calculators for calculating walls can be used for each of these materials.

To calculate the number of blocks or bricks, the online construction calculator will request the following data:

the total length of all walls of the house (perimeter, m);

area of ​​door and window openings;

the thickness of the building walls (the thickness can be half a block, as well as 1, 1.5 or 2-2.5 blocks);

The width of the masonry is 2 bricks

weight and price of one block (kg and rub.);

thickness of the mortar in the masonry (cm) - usually this indicator ranges from 3 to 10 mm;

height of walls at corners (cm);

type and size of future blocks: length, width and height (mm), and some calculators allow you to take into account the voids of blocks, which is used in a number of calculations.

Building Blocks Options

Important! In some calculators, the thickness of the masonry joint is not indicated separately. This means that either it is not taken into account at all, or the “format” rule applies, in which the dimensions of a unit of building material are increased by 1 cm (by the standard seam thickness).

Based on all these indicators, the total area, weight and cost of the masonry are calculated. Approximately the cost of constructing block (brick) walls will be 1/3 of the cost of building the entire house.

What is pre-calculated during the construction of frame houses?

The frame-type house construction calculator allows you to pre-calculate the approximate amount of materials before contacting the specialists of the selected construction company.

To prepare an estimate, the following parameters are calculated:

foundation (for the construction of ordinary frame houses, a pile foundation is excellent, and in the case of unstable soil or for a heavier cottage, a strip or slab foundation);

the amount of material required for insulation - calculated depending on local climatic conditions;

roof dimensions - there is a significant difference between a regular roof and an attic roof;

parameters of utility networks and other communications - not a single calculator can provide all the nuances;

amount of wind and vapor barrier materials;

external and internal finishing of the future building - depending on the selected materials.

To correctly select the foundation and type of roof, it is necessary to perform a detailed calculation of the specific gravity of the walls, floors and roof. Depending on the size of the cladding material, the dimensions of the building and the roof structure, builders select a transverse or rack beam for the load-bearing structure of the house.

The basis of any frame house is the upper and lower frame, which also need to be calculated - both in terms of strength and in terms of the volume of building materials used. The cross-sectional area of ​​the timber is usually taken as the basis here.

Calculation of the amount of finishing materials

To calculate the construction of a house, it is important to determine the amount of finishing material for the walls. One of the most common materials is various types of lining, using an example of which you can consider the nuances of calculations.

The first parameter that affects the price is the type of lining (wooden or plastic), which determines its dimensions.

Wooden lining is a natural material that is durable and has a long service life. The only drawback of this building material is its high susceptibility to moisture content in the air, which is why it is necessary to include various impregnations, varnishes or paints in the estimate. The dimensions of the lining vary in the following ranges: length - from 210 cm to 600 cm; width – 8, 10, 11, 12, 15 cm; thickness: 1.3 cm, 1.6 cm, 1.9 cm, 2.5 cm.

Plastic lining has an increased service life and absolute moisture resistance, making it excellent for finishing the exterior surfaces of a house. For this type of lining, the dimensions will be as follows: length - from 300 cm to 600 cm; width – 10, 12.5 or 15, 20, 25 cm; thickness: 5, 7, 8, 10 mm.

Calculating the amount of lining using an online calculator

To calculate the required amount of lining, the following data is used:

number of windows, their height and width;

number of doors and their sizes;

building perimeter and wall height.

Knowing the area of ​​the building facades and the area of ​​a unit of facing material, you can calculate the amount of lining or other type of siding by dividing the first by the second. The same thing happens when calculating floor coverings inside the house.

Such a building materials calculator will also help calculate the number of specific elements, for example, cornices, strips (starting or finishing), soffits, trims, and other things.

Also, when calculating finishing materials for interior work, the volumes and quantities of paint or wallpaper, flooring and plaster are taken into account.

Video example of calculating the amount of linoleum required:

The consumption of many of them (for example, primers or paints) is indicated on the label by manufacturers. Therefore, you only need to know the coverage area (height times width, minus the area of ​​windows or doors).

Universal online calculators

To determine the approximate cost of the entire construction, a universal, easy-to-use construction calculator is used. This program is designed to perform a preliminary calculation of the price of a house, taking into account the basic parameters.

Online calculator for calculating building materials

By choosing a specific construction technology using a construction calculator, you can quickly compare the cost of building a building in different configurations.

When calculating the cost of construction using an online calculator, the following indicators are taken into account:

foundation type;

area of ​​the house;

number of storeys;

type of roof;

type of floors (material used for their construction);

types of construction and finishing materials.

In universal calculators, it is possible to enter the dimensions of the building (height, width and length), as well as window and door openings, certain dimensions of each room, the depth and width of the foundation, the angle of the roof and the type of heating.

An example of an online calculator for calculating the cost of a turnkey house

For example: building an economy option (a one-story cottage with an area of ​​up to 80 sq. m) can cost 1 million rubles or more. Basic two-story houses with an area of ​​150 square meters. m, will cost at least 2 million rubles. The highest price will be for the construction of large and spacious premium class mansions with a total area of ​​more than 350 sq. m. m – from 5 million rubles.

Conclusion

The main purpose of using an online calculator is to save time. The program makes it possible to calculate the approximate cost of building a house quickly and easily. However, it is worth considering that such software implies a considerable error in the calculations. Accordingly, accurate results can only be obtained from a specialized company.

Using an online calculator, it is easier to decide on a suitable project for your future home. The process of calculating the cost of a house is not influenced by the human factor, and the application itself is often free and accessible to everyone. And yet, in order to reduce errors in calculations to a minimum, it is recommended to contact specialized companies with experienced craftsmen.

Regardless of whether you want to build a house from timber or brick, you definitely need calculation of building materials, which will be used for the foundation at the beginning and finishing at the end, not to mention the roofing.

You are about to build a house. This is a very serious undertaking and, undoubtedly, you decided to approach it with all responsibility. This means that it must be decided what the external and internal walls will be made of, what kind of ceilings and floors there will be (this is not always the same thing), what material will be laid on the roof. If the cottage is made of brick, this does not mean at all that you will not need boards or hardware. Therefore, we begin to compile a list of everything necessary in order to then calculate the building materials.

Foundation calculator

The foundation is the basis of everything, so let’s look at it first. There are options here. Most often, in order to save money, a tape type is made. That is, a ditch is dug strictly along the perimeter of the building, which is filled either with ready-made reinforced concrete blocks with additional cement filling, or simply with concrete mortar. Therefore, you at a minimum need sand, crushed stone and water in certain proportions. To lay blocks, which are quite large in size, into a trench, you will need to use a crane. A columnar foundation is less commonly used, which will save a lot of building materials; even less often, houses are built on wooden piles, which are separate beams or logs.

The calculation of rafter legs can be performed separately or combined with the calculation of the amount of timber for building a house. In addition, it is quite possible that the project will include metal trusses, which means it will be necessary to purchase hardware, at least a corner, or pipes with a square or rectangular profile. This will require additional calculations of rolled metal, especially with regard to the resistance of the structure to loads. The amount of roofing covering is calculated separately, based on the roof area and its shape, for example, a multi-gable version will require more materials due to the high percentage of waste.

The foundation of any building must be reliable, and if the cottage is built from ordinary brick or gas silicate, we discard the piles immediately. Let's focus on strip and columnar foundation options, without reinforced concrete blanks, so as not to involve equipment. Typically, pouring under a house is done in a ratio of 1:3:5 or 1:4:4 cement, sand and crushed stone, respectively. It is much more important to choose the right amount of water; for this, the W/C ratio is used, that is, dividing the volume of water by the mass of cement. You can also use the table of ready-made W/C results, thanks to which, knowing the amount of cement, it will be easy to calculate how much water is needed:

The volume of the strip foundation is determined by the formula V=SL, Where S is the cross-sectional area of ​​the fill, and L– its length, consisting of the perimeter of the building, added to the lintels for the internal walls. A columnar foundation is defined in a slightly different way; the formula looks like V=SHn, Where S– cross-sectional area of ​​the support, H is its height, and n– number of pillars. The cross-section of a square or rectangular base is determined by the formula S=ab, Where a And b– lengths of the sides. The round cut of the support is calculated as follows: S=πR 2, Where R is the radius, and π – constant equal to 3.14.

The number of blocks that will be needed to build walls can be calculated in several ways. It is usually known in advance how many units of ordinary brick or gas silicate are in a cubic meter. Now it is enough to find out the volume of the walls, for which we multiply the area of ​​each by the thickness and subtract from the result the sum of the areas of window and door openings. However, in this case the result will be slightly overestimated, since we did not take into account the angles. In order for the calculation of building materials to be correct, we determine the error. It is enough to carry out the same calculations for the area of ​​the internal walls and subtract the second result from the first. Now all that remains is to multiply the total by one cube, and we get the total amount of materials. You can also use the table:

Number of blocks in 1 m2 of masonry

If you want to build a good-quality log house or a small bathhouse, you will need to determine the height of the building in the crowns, which will build up the walls row by row. But, first of all, it is recommended to find out how many beams or logs, given their dimensions, are contained in one cubic meter. If the cross-section is large enough, rest assured that the number of woodworking products will amount to only a few units. Let's start by determining the volume of one product, with an eye to the cross-sectional shape.
