#### Question

A village having a population of 4000 requires 150 litres of water per head per day. It has a tank measuring 20 m × 15 m × 6 m. For how many days will the water of this tank last?

#### Solution

Given that

Length of the cuboidal tank(l)=20m

Breath of the cuboidal tank (b) = 15m.

Height of cuboidal tank (h)=6 m

Height of the tank`=lxxbxxh=(20xx15xx6)m^3`

`=1800m^3`

`=1800000 liters.`

Water consumed by people of village in one day

`=4000xx150 litres.`

`=600000 litres.`

Let water of this tank lasts for n days

Water consumed by all people of village in n days = capacity of tank

`nxx600000=1800000`

`n=3`

Thus, the water of tank will last for 3 days.
