Question

A swimming pool is 30 m long, 10 m wide, and 2.5 m deep. Its walls have been covered with tiles of size 20 cm x 10 cm. Find the number of tiles to be used on its floor and four walls. 1.75,000 tiles 2.60,000 tiles 3.45,000 tiles 4.30,000 tiles

Answer 1

To find the number of tiles to be used on the floor and four walls of the swimming pool, we need to calculate the total surface area of the floor and four walls, and then divide it by the area of each tile.

The total surface area of the floor and four walls is: (2 x length x height) + (2 x width x height) + (length x width)

Plugging in the values: (2 x 30 x 2.5) + (2 x 10 x 2.5) + (30 x 10) = 150 + 50 + 300 = 500

Each tile has an area of 20 cm x 10 cm = 200 cm² = 0.02 m²

Therefore, the number of tiles required is 500 m² / 0.02 m² = 25,000 tiles.
