Question

A swimming pool is 15m long and 10m wide. how many kilolitres of water must be pumped into it so as to raise the level of water by 3 m?

Answer 1

length of the swimming pool =15m
it's breadth =10 m

we have to raise it by 3m so we can assume that as height of the pool.
therefore, height =3m

volume of the pool =length *breadth *height
=15*10*3
=450m³
=450 kilolitres
hence,
we have to pump 450 kilolitres of water to raise the pool by 3m.

hope this helps.
please correct me if I'm wrong

Answer 2

Length of the swimming pool =15m

Its breadth =10 m

We have to raise it by 3m so we can assume that as the height of the pool.

Therefore, height =3m

Volume of the pool =length *breadth *height

=15*10*3

=450m³

=450 kilolitres

Hence, we have to pump 450 kilolitres of water to raise the pool by 3m.
