The volume of the pentagonal prism to the nearest hundredth is 24.28 cubic inches.

The figure in the image is a pentagonal prism.

The volume of a pentagonal prism is expressed as:

Volume = area of base × height

Volume = 5/2 × a × b × h

Where a is the apothem, b is the base and h is the height.

From the figure:

Apothem a = 0.87 inches

Base b = 2.13 inches

Height h = 5.24 inches

Volume =?

Plug these values into the above formula and solve for the volume:

Volume = 5/2 × a × b × h

Volume = 5/2 × 0.87 × 2.13 × 5.24

Volume = 24.28 cubic inches.

Therefore, the pentagonal prism has a volume of 24.28 cubic inches.
