Question

Какое наименьшее количество плиток размером 20*40 см потребуется, чтобы замостить пол в комнате размером 600*600 см?

Answer 1

600*600 = 360000 см^2
Площадь плитки = 20*40 = 800 см^2
360000:800=450 - плиток понадобится

Answer 2

Calculating the Number of Tiles Needed

To calculate the number of tiles needed to cover the floor of a room measuring 600*600 cm with tiles of size 20*40 cm, we can use the following approach:

1. Calculate the Area of the Room: - The area of the room is given by the product of its length and width. - The area of the room = 600 * 600 = 360,000 square centimeters.

2. Calculate the Area of a Single Tile: - The area of a single tile is given by the product of its length and width. - The area of a single tile = 20 * 40 = 800 square centimeters.

3. Determine the Number of Tiles Needed: - Divide the total area of the room by the area of a single tile to find the number of tiles needed. - Number of tiles needed = Area of the room / Area of a single tile = 360,000 / 800 = 450 tiles.

Therefore, the minimum number of tiles with dimensions 20*40 cm required to cover the floor of a room measuring 600*600 cm is 450 tiles.
