what is the surface area of this rectangular prism?
sa = ft²

Question

Accepted Answer

# Explanation:
## Step1: Recall the formula for the surface area of a rectangular prism
The formula for the surface area $SA$ of a rectangular prism with length $l$, width $w$, and height $h$ is $SA = 2(lw+lh + wh)$

## Step2: Identify the values of $l$, $w$, and $h$
Here, $l = 8$ ft, $w=9$ ft, $h = 7$ ft

## Step3: Substitute the values into the formula
$$
\begin{align*}
SA&=2((8\times9)+(8\times7)+(9\times7))\
&=2(72 + 56+63)\
&=2(191)\
&=382
\end{align*}
$$

# Answer:
$382$
