Surface Area of Cube
To calculate the surface area of a cube we need to know a length of its edge. The surface area of a cube is information which is useful to determine how big amount of material we need to cover a cube or something what has the similar form. The elementary unit of the surface area is one square metre, it means the second power of one metre (1 m2).
Surface Area of Cube - formula
Surface Area of Cube = 6 × side length × side length
S = 6 × a × a = 6 × a2
