Chapter 0.10, Problem 1E

To determine

The surface area of rectangular prism.

Answer to Problem 1E

The surface area of rectangular prism is ${\text{A=64in}}^{\text{2}}$ .

Explanation of Solution

Given :

l = 6 in

w = 1 in

h = 4 in

Calculation: Surface area of rectangular prism:

  $\begin{array}{l}\text{A=2}\left[\text{wl+hl+hw}\right]\\ \text{here,}\\ \text{A=Surface}\text{area}\\ \text{h}\text{=}\text{height}\\ \text{w=}\text{width}\\ \text{l=}\text{length}\end{array}$

So,

Surface area of rectangular prism:

  $\begin{array}{l}\text{A=2}\left[\text{wl+hl+hw}\right]\\ \text{A=2}\left[\text{4+24+4}\right]\\ \text{A=2}\left[\text{32}\right]\\ {\text{A=64in}}^{\text{2}}\end{array}$

Therefore, surface area of rectangular prism is ${\text{A=64in}}^{\text{2}}$ .
