Answer: 104 square inches

Explanation:

The surface area of a prism is the sum of the surface are of all of it's faces.

We can turn that into this equation SA = 2(w x l) + 2(l x h) + 2(w x h) where w is width, l is length, h is height, and 2(w x l) is the top and the bottom surface areas, 2(l x h) is the left and right sides, and 2(w x h) is the front and back.

Substitute to get this: SA = 2(6 x 2) + 2(2 x 5) + 2(6 x 5)

Simplify with multiplication to get this: SA = 24 + 20 + 60

Simplify with addition to get this: SA = 104

Add the unit label and you get 104 square inches.
