# Find the capacity of water tank, in litres, whose dimensions are 4.2 m, 3 m and 1.8 m?

**Solution:**

The capacity of the water tank is given by finding the volume of the water tank. The volume of the water tank is calculated as shown below:

Volume of Water Tank = 4.2 m × 3 m × 1.8m = 22.68m³

1m³ = 1000000cm³

I litre = 1000cm³

Therefore 22.68m³ = 22680000cm³ = 22680 litres

Hence the capacity of the water tank is 22680 litres

**✦ Try This:** Find the capacity of water tank, in litres, whose dimensions are 5.2 m, 2 m and 1.2 m?

The capacity of the water tank is given by finding the volume of the water tank. The volume of the water tank is calculated as shown below:

Volume of Water Tank = 5.2 m × 2 m × 1.2m = 12.48m³

1m³ = 1000000cm³

I litre = 1000cm³

Therefore 12.48m³ = 12480000cm³ = 12480 litres

Hence the capacity of the water tank is 12480 litres
