Question

if a rectangular square pyramid has the square base of 3in and the height of 4 in, what is the volume?

Answer 1

12in^3

Explanation:

v = (1/3) b^2 * H

b^2 = base length^2

(1/3) 3^2 * 4 = 12

1/3 of 9 = 3 x 4 = 12

Answer 2

Volume of a pyramid = Length x width x height / 3

A square base means both the length and width are the same.

Volume = 3 x 3 x 4 /3 = 12 square inches.
