Question

Кафельная плитка имеет форму квадрата со стороной 15 см. Сколько потребуется плиток для укладки кафелем стены высотой 1,5 м и длиной 3,4 м?

Answer 1

Ответ:

≈227 шт.

Объяснение:

Площадь одной плитки 0,15*0,15 м= 0,0225 м²

Площадь стены 1,5*3,4 м - 5,1 м²

Для укладки стены потребуется 5,1 / 0,0225 ≈227 шт.

Answer 2

Calculation of Tiles Needed for Wall Tiling

To calculate the number of tiles needed to tile a wall, we need to determine the area of the wall and the area covered by each tile.

Given: - The tile has a square shape with a side length of 15 cm. - The wall has a height of 1.5 m (150 cm) and a length of 3.4 m (340 cm).

To calculate the area of the wall, we multiply the height by the length: - Area of the wall = height × length = 150 cm × 340 cm = 51,000 cm².

To calculate the area covered by each tile, we square the side length of the tile: - Area of each tile = side length × side length = 15 cm × 15 cm = 225 cm².

To find the number of tiles needed, we divide the area of the wall by the area of each tile: - Number of tiles = area of the wall / area of each tile = 51,000 cm² / 225 cm² = 226.67.

Since we cannot have a fraction of a tile, we round up to the nearest whole number: - Number of tiles needed = 227.

Therefore, you will need 227 tiles to tile a wall with a height of 1.5 m and a length of 3.4 m.

Please note that this calculation assumes there are no obstructions on the wall, and we are not accounting for any wastage or additional tiles for cuts or replacements.
