Answer 1

To calculate the surface area of a cube, you can use the formula:

\[
\text{Surface area} = 6 \times s^2
\]

where \( s \) is the length of an edge of the cube.

Given that each edge of the cube is 12 inches, you can substitute that value into the formula:

\[
\text{Surface area} = 6 \times (12 \text{ in})^2
\]

Calculating \( (12 \text{ in})^2 \):

\[
(12 \text{ in})^2 = 144 \text{ in}^2
\]

Now, substitute back into the surface area formula:

\[
\text{Surface area} = 6 \times 144 \text{ in}^2 = 864 \text{ in}^2
\]

Therefore, the surface area of the cube is \( \boxed{864} \) square inches.
