Question

A swimming pool has to be tiled completely with square tiles of side 60 cm. Find the area of the surface to be tiled, if the dimensions of the pool are 8 m x 3.5 m × 7.5 m. Find the minimum number of tiles required. Calculate volume occupied the cost of tiling at the rate of 7 80 per square meter,

Answer 1

Step-by-step explanation:

Length of swimming pool l=30m

Breadth of swimming pool b=20m

Height of swimming pool h=1.5m

The total surface area of pool= Lateral surface area + Area of base

=2h(l+b)+(l×b)

=2×1.5(30+20)+(30×20)

=750m

2

Side of square tile a=50cm=0.5m

Area of 1 tile =a×a=0.5×0.5=0.25m

2

Number of tiles =

area of tile

area of pool

=

0.25

750

Number of tiles =3000

Therefore 3000 tiles are required
