The volume of the cube is found out by using the formula (length)^3.

The volume of the cuboid is calculated by using the formula, length * breadth * height.

For solving these types of examples we should make sure that all the dimensions are having the same unit. If units are not same then we should make them same.

Some important conversions are given below –

1 m = 100 cm, 1 mm =0.1 cm, 1 litre = 1000 cubic centimetres.

If we know the formula and if we can do simple mathematical calculations then we can solve examples of this practice set very easily.
