Q4 of 12 Page 108

For rainwater harvesting, a tank of length 10 m, breadth 6 m, and depth 3m are built. What is the capacity of the tank? How many liters of water can it hold?

Given:


Length of tank = 10 m


Breadth of tank = 6 m


The height of tank = 3 m


Capacity is nothing but the volume of the tank.


As for length, breadth and height are given, the tank is cuboidal in shape.


The volume of tank = l × b × h


= 10 × 6 × 3


= 180 m3


The capacity of the tank is 180 m3


Now,


1 m3 = 1000 litre


∴180 m3 = 180 × 1000 = 180,000 litre


∴ The tank can hold 180,000 litres of water
