Answer: Shouldn't have procrastinated but I'm feeling benevolent
Explanation:
We first find the surface area of every face.
7 * 2 = 14
7 * 1 = 7
2 * 1 = 2
add these up to get a surface area for three sides.
14 + 7 + 2 = 23
Since a rectangular prism has 6 sides, the next three sides are identical to the previous three.
23 * 2 = 46.
46 is our answer.
