what is the volume of the recangular pyrimid? round answer to neareast hundthreth in decimal form? length: 16 mi width; 16 mi altitude: 8 mi

The volume of a rectangular pyramid is given by the formula V = (1/3) * length * width * altitude.

Plugging in the values:
V = (1/3) * 16 mi * 16 mi * 8 mi
V = (1/3) * 2048 mi^3
V = 682.67 mi^3

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