Question

Папа Карло и Буратино делали ремонт. Им необходимо подсчитать количество досок длиной 5 м а шириной 50 см, чтобы настелить полы в комнате в виде квадрата со сторонами 10 м.

Answer 1

1) 10 * 10 = 100(кв.м) - площадь пола
2) 5 * 0,5 = 2,5(кв.м) - площадь одной доски
3) 100 : 2,5 = 40 (досок) потребуется
Ответ: 40 досок потребуется, чтобы настелить полы в комнате.

Answer 2

10 :5=2 доски нужно в длину;    50 см=0,5 м10 :0,5= 20 досок нужно в ширину20 * 2 = 40 досок нужно для настилки полов

Answer 3

Calculating the Number of Boards Needed for the Room

To calculate the number of boards needed to cover the floor of the room in the form of a square with sides of 10 meters, we can use the following approach:

1. Calculate the Area of the Room: - The area of the room can be calculated by multiplying the length and width of the room. In this case, the room is in the form of a square with sides of 10 meters, so the area can be calculated as 10 meters * 10 meters.

2. Calculate the Area of Each Board: - The area of each board can be calculated by multiplying the length and width of the board. In this case, the length of the board is given as 5 meters and the width as 50 centimeters. It's important to convert the width to meters before proceeding with the calculation.

3. Divide the Area of the Room by the Area of Each Board: - By dividing the area of the room by the area of each board, we can determine the number of boards needed to cover the entire floor.

Let's proceed with the calculations.

Calculation Steps

1. Calculate the Area of the Room: - Area of the room = 10 meters * 10 meters = 100 square meters.

2. Convert the Width of the Board to Meters: - 50 centimeters = 0.5 meters.

3. Calculate the Area of Each Board: - Area of each board = 5 meters * 0.5 meters = 2.5 square meters.

4. Divide the Area of the Room by the Area of Each Board: - Number of boards needed = Area of the room / Area of each board - Number of boards needed = 100 square meters / 2.5 square meters = 40 boards.

So, 40 boards of the given dimensions are needed to cover the floor of the room in the form of a square with sides of 10 meters.
