What is the formula for the surface area of a cube?

6s²

The formula for the surface area of a cube is derived from the fact that a cube has six identical square faces. To calculate the surface area, you first determine the area of one of those squares, which is given by the formula \(s^2\), where \(s\) is the length of a side of the cube. Since there are six of these square faces, the total surface area of the cube can be found by multiplying the area of one face by the number of faces:

\[

\text{Surface Area} = 6 \times s^2 = 6s^2.

\]

This demonstrates how each aspect of the cube’s geometry contributes to the overall surface area, emphasizing the uniformity and replication of the square faces. The other options represent incorrect calculations or misunderstandings of how to sum the areas of the cube's faces.
