The length, breadth and height of a water tank are 5 m, 2.5 m and 1.25 m respectively. Calculate the capacity of the water tank in:

a. m³

b. litre

Length = 5 m; breadth = 2.5 m; height = 1.25 m

a. Volume of water tank = length x breadth x height = 5 m x 2.5 m x 1.25 m = 15.625 m³

So, capacity of water tank in m³ = 15.625 m³.

b. 1 m³ = 1000 L
15.625 m³ = 15.625 x 1000 = 15625 L

So, capacity of water tank in litres = 15,625 L.
