Question

a swimming pool has 120 kilolitres of water. if the width of the pool is 4 m and the depth of water is 2 m, what is the length of the pool

Answer 1

ANSWER :

Capacity of pool = 120 kilo litres

Depth of pool ( h ) = 2m

Width of the pool ( b ) = 4m

Length of pool ( l ) = ?

Note that here, the volume of the pool is given in litres. So convert the capacity of the pool to m^3

=> 1 kilo litre = 1 m^3

=> 120 kilo litres = 120 m^3

Therefore, the volume of the pool is 120 m^3

Volume of pool = l x b x h

=> 120 = l x 4 x 2

=> l = 120/8 = 15

Therefore,the length of the pool will be 15m

Hope this helps you☺☺

Answer 2

Answer:

Capacity of the pool = 120kl

Depth of pool (h) = 2m

Width of the pool (b) = 4m

Length of the pool (l) = ?

1kl = 1m^3

120kl = 120m^3

Volume of pool = l * b* h

120 = l * 4 * 2

l = 120/8

l = 15
