Question

Accepted Answer

# Explanation:
## Step1: Recall the formula for the surface area of a rectangular prism
The formula for the surface area $S$ of a rectangular prism with length $l$, width $w$, and height $h$ is $S = 2(lw+lh + wh)$. Here, $l = 3$ in, $w = 1$ in, and $h = 8$ in.
## Step2: Substitute the values into the formula
$$
\begin{align*}
S&=2((3\times1)+(3\times8)+(1\times8))\
&=2(3 + 24+8)\
&=2\times35\
& = 70
\end{align*}
$$

# Answer:
$70$
