Use the image to answer the question.
An illustration shows a rectangular pyramid with length of 7.5 miles, a width of 7 miles, and a perpendicular height of 5 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?
(1 point)
The volume of a rectangular pyramid is given by the formula V = (1/3) * base area * height.
First, calculate the base area of the rectangular pyramid:
Base area = length * width
Base area = 7.5 miles * 7 miles
Base area = 52.5 square miles
Now, plug the base area and the height into the formula:
V = (1/3) * 52.5 * 5
V = (1/3) * 262.5
V = 87.5 cubic miles
Therefore, the volume of the rectangular pyramid is 87.5 cubic miles.
