Chapter 12.1, Problem 7WE

To determine

To complete: the table.

Answer to Problem 7WE

$e$	3	$e$	?	?	?	2 $x$
$\text{T}\text{.A}\text{.}$	$54$	?	?	?	150	?
$V$	$27$	?	1000	64	?	?

Explanation of Solution

Given information:

$e$	3	$e$	?	?	?	2 $x$
$\text{T}\text{.A}\text{.}$	?	?	?	?	150	?
$V$	?	?	1000	64	?	?

Calculation: to complete the table,

  $e=3$

  $\begin{array}{l}V=Bh\\ V=\left(9\right)\left(3\right)\text{ [substitute]}\\ V=27\text{ [simplify]}\end{array}$

  $\begin{array}{l}\text{T}\text{.A}\text{.=L}\text{.A}+2B\\ \text{T}\text{.A}\text{.}=\left(4{\left(3\right)}^2\right)+2\left({\left(3\right)}^2\right)\text{ [substitute]}\\ \text{T}\text{.A}\text{.}=54\text{ [simplify]}\end{array}$
