Answer:
B. 225 cubic inches
Step-by-step explanation:
The volume is the product of the base area and the height:
V = Bh
The area of the square base is the product of the side lengths:
B = (5 in)^2 = 25 in^2
For a height of 9 in, the volume is ...
V = (25 in^2)(9 in) = 225 in^3
The volume of the right rectangular prism is 225 cubic inches.
