Answer:
105 in³
Explanation:
You want the volume of a pyramid with a rectangular base 5 inches by 9 inches, and a height of 7 inches.
Base
The area of the base is ...
A = LW
A = (9 in)(5 in) = 45 in²
Volume
The volume is given by the formula ...
V = 1/3Bh
where B is the area of the base, and h is the height.
V = 1/3(45 in²)(7 in) = 105 in³
The volume of the pyramid is 105 cubic inches.
