Chapter 12.1, Problem 9WE

To determine

To complete: the table.

Answer to Problem 9WE

$e$	3	$e$	$10$	?	?	2 $x$
$\text{T}\text{.A}\text{.}$	$54$	$6e^2$	$600$	?	150	?
$V$	$27$	$e^3$	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,

  $T.A=1000$

  $\begin{array}{l}V=Bh\\ 1000=\left(e^2\right)\left(e\right)\text{ [substitute]}\\ e=10\text{ [simplify]}\end{array}$

  $\begin{array}{l}\text{T}\text{.A}\text{.=L}\text{.A}+2B\\ \text{T}\text{.A}\text{.}=\left(4{\left(10\right)}^2\right)+2\left({\left(10\right)}^2\right)\text{ [substitute]}\\ \text{T}\text{.A}\text{.}=600\text{ [simplify]}\end{array}$
