Question

diane wants to decorate a rectangular box for a gift

Answer 1

Given:

There are given the height, length, and width.

Where,

$\begin{gathered} l=14in \\ h=3in \\ w=8in \end{gathered}$

Explanation:

According to the question:

We need to find the surface area of the box:

Then,

To find the value, we need to use the surface area of a rectangular box:

So,

From the formula of the surface area of the rectangle box:

$SA=2lw+2lh+2wh$

Then,

Put the height, width, and length into the given formula:

$\begin{gathered} SA=2lw+2lh+2wh \\ SA=2(14)(8)+2(14)(3)+2(8)(3) \\ SA=224+84+48 \end{gathered}$

Then,

$\begin{gathered} SA=224+84+48 \\ SA=356 \end{gathered}$

Final answer:

Hence, the correct option A.
