What is the surface area of a cube?

62. What is the surface area of a cube?

1. Surface_area=6*A
2. Surface_area=6*A²
3. Surface_area=6*A³
4. Surface_area=3*A²

Answer

The correct answer is: B) Surface_area=6*A²

Explanation

All six faces of a cube are equal squares, and each face has an area of A * A = A2. Because a cube has six faces, its total surface area (SA) equals the sum of the areas of all six faces, as given by: Surface_area = 6 * A²
