How do you find the surface area of a cube?

The surface area of a cube can be found by finding the length of any of the cube's edges, then multiplying that length by itself, then multiplying its product by six. This equation can be written as A=6e^2, where e stands for the length of any of the cube's edges.

The surface area of any polyhedron is found by taking the area of each face and adding them all together. A cube is a special kind of rectangular prism in which each face is a square, meaning that every face has the same area. The cube is the only regular hexahedron, or six-sided regular polyhedron.
