Answer 2

The formula of the area of a cube is 6$a^{2}$.

Explanation:

The definition of surface area of a given cube expresses that if the total surface area is equivalent to the sum of all the areas of the faces of the cube. Since the cube has six faces, therefore, the total surface area of the cube will be equivalent to sum of all six faces of cube.

We know that the surface of the cube is in square shape. Therefore, the area of each face of the cube is equivalent to the area of a square.

Thus, let's assume that the length of edge of cube is a.

Therefore, area of one face of a cube = $a^{2}$  

As there are 6 faces in a cube, the total surface area of a cube will be,

                      TSA = $a^{2} + a^{2} +a^{2} +a^{2} +a^{2} +a^{2}$

Therefore, TSA of cube = 6$a^{2}$
