What is the formula to find the surface area of a cube?

The formula for finding the surface area of a cube is derived from understanding that a cube has six identical square faces. Each face of the cube has an area that can be calculated as the length of one side squared (side × side). Since there are six faces, the total surface area is calculated by multiplying the area of one face by the number of faces, leading to the formula Surface Area = 6 × side^2.

This correctly captures the total area of all the surfaces that make up the cube. In this case, choosing the correct formula means recognizing that the dimensions of a cube are uniform and that the surface area measurement requires consideration of all faces, not just one or two. The other options do not properly represent the surface area of a cube because they either miscalculate the number of faces or use incorrect dimensions in the formula.
