Answer:

answer is 52 square inches.

Explanation:

The formula for surface area for any prism is (2 x Area of base) + (perimeter of base x depth)

1. The base I will choose is the 4 inch by 2 inch side.

We multiply it (4x2) to get 8 then times it by two to complete the first part of the formula:

16 + (perimeter of base x depth)

2. We have to refer to the same base so the 4 x 2 base will have a perimeter of 4 + 2 + 4 + 2 = 12. Then we times by the depth which is 3 in this case.

Thus we have 16 + (12 x 3) =

16 + 36 =

52.
