To find the surface area of a cube, you can use the formula:
\[ SA = 6s^2 \]
where \( s \) is the length of each side of the cube. Given that the side length is \( 3 \) feet, we can substitute \( s \) into the formula:
1. Calculate \( s^2 \):
\[
s^2 = 3^2 = 9 \text{ square feet}
\]
2. Now multiply by 6 to find the surface area:
\[
SA = 6 \times 9 = 54 \text{ square feet}
\]
Thus, the surface area of the cardboard box is **54 square feet**.
