Question

A rectangular swimming pool 30m long, 20m wide and 1.5m deep is to be tiled . If each tile is 50cm×50cm, how many tiles will be required?​

Answer 1

Answer:

3000

Step-by-step explanation:

Find total surface area = 2(lb + bh+hl) and subtract (30*20) because top of the pool is not to be tiled.

Divide this by (0.5 m * 0.5 m ) = 0.25 m = 1/4 m

Answer = 750/ 0.25 = 3000 tiles.
