The surface area of a cube can be found using the formula:
\[ \text{Surface Area} = 6s^2 \]
where \( s \) is the length of one side of the cube. This means you take the length of one side, square it (multiply it by itself), and then multiply that result by 6, since a cube has 6 faces.
So, if you know the length of a side of the cube, just plug that value into the formula to find the surface area!
