# Diagonal of a Cube Calculator

A cube is a three-dimensional shape or object with six squared faces. The intersection of two faces is called an edge and the meeting point of three edges is called a vertex. A cube has six faces or facets or sides, twelve edges and eight vertices. Find out the length of the diagonal of a cube using this online Diagonal of a cube calculator for the given values of the edge of cube. Just enter the edge and click on calculate to know the diagonal of the cube.
