Question

в санатории построили бассейн прямоугольной формы ,длинна которого 15 м ,ширина 5 м и глубина 2м. Сколько квадратных кафельных плиток со стороной 1дм каждая потребовалось для облицовки дна этого бассейна? стенок этого бассейна?

Answer 1

15*5*2=150(м объёма  бассейна)

15м=15000см 

1дм=10см

15000/10=1500(шт  плитка для  облицовки  бассейна)

 

 

 

 

 

 

Answer 2

Calculation of Tiles for the Pool Bottom

To calculate the number of square tiles required to cover the bottom of the rectangular pool, we need to determine the area of the pool and the area of each tile.

The pool has a length of 15 meters, a width of 5 meters, and a depth of 2 meters.

To find the area of the pool's bottom, we multiply the length by the width:

Area of the pool's bottom = Length × Width = 15 m × 5 m = 75 square meters

Each tile has a side length of 1 decimeter (0.1 meters), which means it has an area of:

Area of each tile = Side length × Side length = 0.1 m × 0.1 m = 0.01 square meters

To determine the number of tiles needed, we divide the area of the pool's bottom by the area of each tile:

Number of tiles for the pool's bottom = Area of the pool's bottom ÷ Area of each tile = 75 square meters ÷ 0.01 square meters = 7500 tiles

Therefore, 7500 square tiles with a side length of 1 decimeter each are required to cover the bottom of the pool.

Calculation of Tiles for the Pool Walls

To calculate the number of square tiles required to cover the walls of the rectangular pool, we need to determine the perimeter of the pool and the area of each tile.

The pool has a length of 15 meters, a width of 5 meters, and a depth of 2 meters.

To find the perimeter of the pool, we add the lengths of all four sides:

Perimeter of the pool = 2 × (Length + Width) = 2 × (15 m + 5 m) = 2 × 20 m = 40 meters

Since the pool has a depth of 2 meters, the height of the wall is also 2 meters.

To find the area of each wall, we multiply the perimeter by the height:

Area of each wall = Perimeter × Height = 40 m × 2 m = 80 square meters

Each tile has a side length of 1 decimeter (0.1 meters), which means it has an area of:

Area of each tile = Side length × Side length = 0.1 m × 0.1 m = 0.01 square meters

To determine the number of tiles needed, we divide the area of each wall by the area of each tile:

Number of tiles for each wall = Area of each wall ÷ Area of each tile = 80 square meters ÷ 0.01 square meters = 8000 tiles

Since there are four walls in the pool, the total number of tiles required to cover the walls is:

Total number of tiles for the pool walls = Number of tiles for each wall × Number of walls = 8000 tiles × 4 = 32000 tiles

Therefore, 32000 square tiles with a side length of 1 decimeter each are required to cover the walls of the pool.

Please note that the above calculations assume that the pool has a rectangular shape and does not take into account any additional factors such as tile wastage, grouting, or irregularities in the pool's shape.
