Answer:
Step-by-step explanation:
Maths
A rectangular swimming pool 8m long, 4m wide and 2m deep is to be tiled. If each tile is 50 cm × 50 cm, how many tiles will be required.
Answer
Length of swimming pool l=8m
Breadth of swimming pool b=4m
Height of swimming pool h=2m
The total surface area of pool= Lateral surface area + Area of base
=2h(l+b)+(l×b)
=2×2(8+4)+(8×4)
=48+32=80
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.
