The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

Answer:

Cube: A cube is a three-dimensional shape which is defined XYZ plane. It has six faces, eight vertices and twelve edges. All the faces of the cube are in square shape and have equal dimensions.

Surface Area of a Cube:

For cube, length = breadth = height

Suppose the length of an edge = l

Hence, surface area of the cube = 2(l × l +l × l + l × l) = 2 x 3l2 = 6l2

Total Surface Area of Cube= 6l2
