6.6 in and the height of the pyramid is 7, point, 7, in
7.7

7.7 in. Round your answer to the nearest tenth of a cubic inch.

Answer 1

111.8 in

Explanation:

The formula for volume of a pyramid is:

V = (L·W·H)/3

Where L = length of one side of the base

W = length of the other side of the base

H = the height

That's generic in case the base is a rectangle, but yours is a square, so L & W are the same:

V = (6.6 x 6.6 x 7.7)/3 = 335.4/3 = 111.8 in
