A square prism has a base with 8-inch sides and a total surface area of 288 square inches. What is the volume of the prism?

Answer: 320 cubic inches

Step-by-step explanation:

Equation for Surface area of this shape:

A = 2a^2+4ah

2a^2+4ah = 288

a = 8

2 x 8^2 + 4 x 8 x h = 288

h = 5

Now volume formula

V = a^2 x h

= 64 x 5

= 320 cubic inches
