The exact calculation of square meters is required mainly when repairing a house or apartment. By the result, you very easily buy exactly the number of wallpaper or tiles that are required for a particular room.
How to calculate square meters - the necessary tools
You will need:
- A special construction roulette or long, at least 1 m, ruler.
- A simple pencil for marks on the walls, ceilings and floors.
- Notebook for notes and a ballpoint pen.
- Calculator.
How to count square meters - the main formula
From the school curriculum, you probably remember that any area that is measured in square meters is calculated by changing only two values: width and length.
S \u003d A*B
where: S is the area (sq.m), a - length (m), b is width (m).
The designations in this formula are applicable to horizontal surfaces, i.e. Paul and ceiling. For vertical walls, does the formula look like this?
S \u003d A*H
where: S is the area (sq.m), a is the length of the wall along the baseboard (m), h is the height of the wall from the floor to the ceiling.
How to count square ceiling or floor meters
The simplest is the calculation of square meters of continuous horizontal surfaces - that is, floor and ceiling. Since the ceiling is a mirror reflection of the floor, you can confidently determine the floor area that the ceiling has the same amount of square meters. So:
- Take the roulette in your hands and fix its tip in the corner of the room near the floor itself. Pull the roulette along the entire wall to the next corner and write the resulting number in the notebook (for example, 6 m). If instead of a long roulette you will use the ruler, then after each shifting the ruler make notes on the floor. The resulting 6 meters is the length (A).
- In the same way, measure the width (b) of the floor. For example, you will get 4 m. Write down this value in a notebook.
- Take the calculator and change the length to the width: 6*4. The result is 24 and will be the number of square meters of floor or ceiling.
How to calculate square meters of a continuous wall
Using a roulette or ruler, measure the length of the wall along the skirting board. For example, it will be 5 m. Next, measure the height of the wall - it is best to do this in the corner. Suppose the height of the room turned out to be 3.3 m. Now change these two values: 5*3.3 \u003d 16.5. The result is 16.5 and will be the same square meters.
How to count square meters walls with a window
For calculation, you will need additional window measurements and standard wall measurements.
- Measure the window height and its width. For example, your height will turn out 1 m, and the width is 1.5 m. Change these two values: 1*1.5 \u003d 1.5 square meters (window area).
- Measure the length of the wall along the skirting board (take the same 5 m) and the height of the wall (take the same 3.3 m). When moving, get 16.5 square meters.
- Of the total number of square meters of wall (16.5), take the number of square meters of the window (this is 1.5). The result will be 15 square meters (16.5-1.5).
How to count square meters walls with a door
The calculation is similar to calculating the square meters of the wall with the window.
Knowing the exact values \u200b\u200bof square meters, you can go to the store and buy wallpaper or tiles for repair. Be sure to contact the consultant and show him all the measurements and calculations. The fact is that all finishing materials must be purchased taking into account the selection of a drawing or cutting tiles - a supply of square meters can be from 10 to 20 %.
