Answer:
62 square units
Explanation:
You want the surface area of a rectangular prism 3 units high, 2 units wide, and 5 units long.
Area
The surface area of a rectangular prism is given by the formula ...
SA = 2(LW +H(L +W))
Application
Using the given dimensions, L=5, W=2, H=3, the area is ...
SA = 2(5·2 +3(5 +2)) = 2(10 +3(7)) = 2(31)
SA = 62 . . . square units
The surface area of the prism is 62 square units.
