1 answer

The formula for the volume of a rectangular pyramid is:

V = (1/3) * base area * height

The base area is given by:

base area = length * width = 14in * 6in = 84 square inches

Given the height of the pyramid is 13.89 inches, the volume is:

V = (1/3) * 84 * 13.89 = 389.72 cubic inches

Rounded to the nearest whole number, the rectangular pyramid contains 390 cubic inches.
