An illustration shows a square rectangular pyramid with a side length of 16 miles and a perpendicular height of 8 miles. The right and front faces are visible. Edges and faces that are not visible are indicated by dashed lines.

What is the volume of the rectangular pyramid? Round answer to nearest hundredth in decimal form.

First, calculate the volume of the rectangular pyramid using the formula: V = (1/3) * base area * height

The base area of the pyramid is the area of the square base, which is (16 miles)^2 = 256 square miles.

Plugging in the values, we get: V = (1/3) * 256 * 8 = 682.67 cubic miles

Therefore, the volume of the rectangular pyramid is approximately 682.67 cubic miles.
