Base area = side * side

Volume = base area * height

Surface = base area * 6

## What is a cube?

A cube is the solid whose calculation is simplest. In a cube, all edges have the same length and are perpendicular.For a cube, those formulas hold: If a is the side length, the volume equals a*a*a, the surface equals 6*a*a and the base area equals a*a. The diagonals on the side has the length a*square root of 2 cause they are diagonals of a square. The diagonal from one corner to the opposite one has the length square root of (a²+a²+a²).

For further information, move your mouse over one of the words and the corresponding part of the cube will be marked.
