# Diagonal of Octahedron Calculator

A regular octahedron is the dual polyhedron of a cube. It is a square bipyramid in any of 3 orthogonal orientations. A regular octahedron is a 3-ball in the Manhattan metric. A diagonal is a line segment joining two vertices of a polygon or polyhedron. Any sloping line is called diagonal. Here is the simple online diagonal of octahedron calculator which helps you to calculate diagonal of an octahedron. Just enter the value of edge length to calculate the diagonal.
