Answer:
C. 5 by 3 by 2
Step-by-step explanation:
The surface area of a rectangular prism is given by:
[tex]2(lw + l h + wh)[/tex]
If the length of the prism is
[tex]l = 5[/tex]
the width of the prism is
[tex]w = 3[/tex]
and the height of the prism is:
[tex]h = 2[/tex]
The surface area becomes:
[tex]2(5 \times 3 + 5 \times 2 + 3 \times 2)[/tex]
Multiply within the parenthesis:
[tex]2(15 + 10+ 6)[/tex]
Add:
[tex]2(31)[/tex]
[tex] = 62[/tex]
square units.
Hence the correct choice is C.
