A. 5 by 3 by 1
B. 2 by 2 by 6
C. 5 by 3 by 2
D. 6 by 2 by 4

Answer 1

c is the answer

Explanation:

Answer 2

C. 5 by 3 by 2

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 * 3 + 5 * 2 + 3 * 2)`

Multiply within the parenthesis:

`2(15 + 10+ 6)`

Add:

`2(31)`

`= 62`

square units.

Hence the correct choice is C.
