Question 6 Volume And Surface Area Of Solids Exercise 15A

A cuboidal water tank is 6m long, 5m wide, and 4.5m deep. How many liters of water can it hold? (Given,1m3 = 1000 litres.)

It is given that

Length of the cuboidal water tank = 6m

Breadth of the cuboidal water tank = 5m

Height of the cuboidal water tank = 4.5m

We know that

Volume of a cuboidal water tank = l × b × h

By substituting the values

Volume of a cuboidal water tank = 6 × 5 × 4.5

By multiplication

Volume of a cuboidal water tank = 135 m3

We know that 1m3 = 1000 litres

So we get

Volume of a cuboidal water tank = 135 × 1000 = 135000 litres

Therefore, the cuboidal water tank can hold 135000 litres of water.
