2. Solution Steps

The surface area of a rectangular prism can be found using the following formula:

$Surface Area = 2lw + 2lh + 2wh$

where $l$ is the length, $w$ is the width, and $h$ is the height.

In this problem, $l = 7$, $w = 7$, and $h = 18$.

Plugging in these values into the formula, we get:

$Surface Area = 2(7)(7) + 2(7)(18) + 2(7)(18)$

$Surface Area = 2(49) + 2(126) + 2(126)$

$Surface Area = 98 + 252 + 252$

$Surface Area = 98 + 504$

$Surface Area = 602$

3. Final Answer

602
