Which formula correctly computes the surface area of a cube with side length s?

Explanation:
Surface area of a cube is found by adding up the areas of all six square faces. Each face has area s^2, so with six faces the total is 6s^2. The other options only account for fewer faces (two, three, or four), so they undercount the total surface area. Since the cube has six faces, the correct formula is 6s^2.
