Question

a swimming pool has 120 kilo litres of water. If the width of the pool is 4m and the depth of the water is 2m, what is the length of the pool

Answer 1

The formula for the volume of cuboid (the swimming pool is cuboid) is

length x width x height= volume

(Depth is height)

so what we do is we suppose length to be 'l'

l x 4 x 2=120

8l=120

l=120/8

l=15

The length is 15 metres
