Answer 2

The surface area of the right rectangular prism is, 22 square inches.

Explanation:

Surface area of the right rectangular prism(A) is given by:

`A =2(wl+hl+hw)` ....[1]

where,

w is the width

l is the length

h is the height of the right rectangular prism respectively.

As per the statement:

A rectangular prism with a length of 3 inches, a width of 1 inch, and a height of 2 inches

⇒
`l = 3` in., w = 1 in. and h = 2 inches.

Substitute these in [1] we have;

`A =2(1(3)+2(3)+2(1))`

A = 2(11)

⇒
`A = 22 in^2`

Therefore, the surface area of the right rectangular prism is, 22 square inches.
