Final answer:

To find the surface area of a prism, you need to find the areas of all the faces and add them together. Thus, surface area is 158 square inches.

Step-by-step explanation:

To find the surface area of a prism, you need to find the areas of all the faces and add them together. In this case, the prism has 5-inch by 3-inch rectangular faces and 8-inch square faces. The formula to find the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Substituting the values, we get:

Surface Area = 2(5)(3) + 2(5)(8) + 2(3)(8) = 30 + 80 + 48 = 158 square inches
