Answer:
C. 5 by 3 by 2
Step-by-step explanation:
The surface area of a rectangular prism is given by:
![2(lw + l h + wh)](https://tex.z-dn.net/?f=2%28lw%20%2B%20l%20h%20%2B%20wh%29)
If the length of the prism is
![l = 5](https://tex.z-dn.net/?f=l%20%3D%205)
the width of the prism is
![w = 3](https://tex.z-dn.net/?f=w%20%3D%203)
and the height of the prism is:
![h = 2](https://tex.z-dn.net/?f=h%20%3D%202)
The surface area becomes:
![2(5 \times 3 + 5 \times 2 + 3 \times 2)](https://tex.z-dn.net/?f=2%285%20%5Ctimes%203%20%2B%205%20%5Ctimes%202%20%2B%203%20%5Ctimes%202%29)
Multiply within the parenthesis:
![2(15 + 10+ 6)](https://tex.z-dn.net/?f=2%2815%20%2B%2010%2B%206%29)
Add:
![2(31)](https://tex.z-dn.net/?f=2%2831%29)
![= 62](https://tex.z-dn.net/?f=%20%3D%2062)
square units.
Hence the correct choice is C.
