A right rectangular prism has a base area of 2 1/2 square inches and a height of 11 1/2 inches

what is the volume of the prism?

To find the volume of a right rectangular prism, you multiply the base area by the height.

Base area = 2 1/2 square inches = 5/2 square inches
Height = 11 1/2 inches = 23/2 inches

Volume = Base area x Height
Volume = (5/2) * (23/2)
Volume = 115/4
Volume = 28 3/4 cubic inches

Therefore, the volume of the prism is 28 3/4 cubic inches.
