Question

A village has a water tank of dimension 20 m x 15 m x 6 m. How many litres of water it can hold. If per day consumption of water is 1000 litres. For how many days will the water of this tank last?

Answer 1

Quantity of water required per day = 1000 litres.

Length, breadth and height of a tank are 20 m, 15 m and 6 m respectively.

Capacity of tank = 20m x 15m x 6m 

= 1800 m³

1 m³ = 1000 litres

1800 m³ = 1800000 litres

Required number of days for which the water of the tank will last

= \(\frac { 1800000 }{ 1000 }\) = 1800 days

Thus, water tank can serve for 1800 days.
