Which rectangular prism has a surface area of 62 square units? [Note: Art is not drawn to scale.]
Nimfa-mama [501]

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)

If the length of the prism is

l = 5

the width of the prism is

w = 3

and the height of the prism is:

h = 2

The surface area becomes:

2(5 \times 3 + 5 \times 2 + 3 \times 2)

Multiply within the parenthesis:

2(15 + 10+ 6)

Add:

2(31)

= 62

square units.

Hence the correct choice is C.
