Question

Find the volume of a pyramid with a square base, where the side length of the base is

8.3 in and the height of the pyramid is 7.3 in. Round your answer to the nearest
tenth of a cubic inch.

Answer 1

The volume of the pyramid is 167.6 cube inch (approx).

Explanation:

Given,

Each length (l) of the base of the pyramid = 8.3 in

Height(h) of the pyramid = 7.3 in

To find the volume of the pyramid.

Formula

Volume of the pyramid =
`(1)/(3)`×area of the base×height

Area of the base = l²

Now,

The volume of the pyramid =
`(1)/(3)`×l²×h

=
`(1)/(3)`×8.3²×7.3 cube inch = 167.6 cube inch (approx)
