Volume of a Rectangular Prism

The volume of a rectangular prism is the space it occupies in the three-dimensional plane. It is measured in cubic units such as m3, cm3, mm3, ft3.

Formula

The formula to calculate the volume of a rectangular prism is given below:

Volume of a Rectangular Prism

In the above formula, the product of the length and the width is the base area of the prism. Therefore, we can also write the formula as:

Volume (V) = Base Area x Height

Solved Examples

Find the volume of a rectangular prism in the figure.

Solution:

As we know,
Volume (V) = l × w × h, here l = 12 cm, w = 6 cm, h = 17 cm
V = 12 × 6 × 17
= 1224 cm3

Find the volume of a rectangular prism whose base area is 49 in2 and height is 12 in.

Solution:

As we know,
Volume (V) = Base Area x Height, here base Area = 49 in2, w = 6 cm, height = 12 in
V = 49 × 12
= 588 in3

Find the volume of an oblique rectangular prism in the figure.

Solution:

As we know,
The volume of an oblique rectangular prism = volume of a right rectangular prism with the same height ‘h’
Volume (V) = l × w × h, here l = 11 cm, w = 9.6 cm, h = 18 cm
V = 11 × 9.6 × 18
= 1900.8 cm3
