Question

A swimming pool is 15m long and 10m wide.How many kilometres of water must be pumped into it as to raise the level of water by 3m? (Hint:Put 1 m3 = 1 kilometre​

Answer 1

Answer:

• V=l*w*h
• V=15*10*3
• V=450 cubic meters of water
• by raising the level of water by 3 m, you are adding 450 cubic meters of water
• 1 kiloliter=1 cubic meter
• you add 450 kiloliters of water

hope this helps you

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.
