What is the volume of the rectangular pyramid? the base is 7mi the width is 7.5mi and hight 5mi

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

First, calculate the base area: A = base * width = 7mi * 7.5mi = 52.5 mi^2

Then, calculate the volume: V = (1/3) * 52.5 mi^2 * 5 mi = 87.5 mi^3

Therefore, the volume of the rectangular pyramid is 87.5 cubic miles.
