A Formula for the Surface area of the cube is 6a².
A cube is a three-dimensional solid with six square faces, facets, or sides, three of which meet at each vertex in geometry. It looks like a hexagon from the corner, and its net usually looks like a cross. One of the five Platonic solids, the cube is the only regular hexahedron.
The sum of the areas on each face of the cube that covers it is the cube's surface area. The formula for surface area is six times the cube's length divided by the square of that number. It is denoted by 6a², where a is the cube's side length. It basically refers to the entire surface area.
area of one face = a² [By area of square formula]
There are six faces altogether. Therefore,
TSA (total surface area) of cube = S = a² + a²+ a² + a² + a² +a²
S = 6a²
