what is the volume of the rectangular pyramid?

Measurements: 5mi, 7.5mi, 7mi

To calculate the volume of a rectangular pyramid, you can use the formula:

Volume = (1/3) x base area x height

Given measurements:
Base length = 5mi
Base width = 7.5mi
Height = 7mi

First, calculate the base area:
Base area = length x width
Base area = 5mi x 7.5mi
Base area = 37.5 square miles

Now, calculate the volume of the rectangular pyramid:
Volume = (1/3) x base area x height
Volume = (1/3) x 37.5 sq mi x 7 mi
Volume = (1/3) x 262.5 cubic miles
Volume = 87.5 cubic miles

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