Base length (a) 14 in

Base width (b) 6 in

Pyramid height (h) 13.89 in

What is the volume of the rectangular pyramid? Round answer to the nearest whole number.

Volume of a rectangular pyramid is given by the formula:

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

First, calculate the base area:
Base area = base length * base width
Base area = 14 in * 6 in
Base area = 84 square inches

Now, calculate the volume of the pyramid:
V = (1/3) * 84 * 13.89
V = 391.32 cubic inches

Rounded to the nearest whole number:
V = 391 cubic inches

Therefore, the volume of the rectangular pyramid is 391 cubic inches.
