# Edge Length of Octahedron Calculator

An Octahedron is with 8 faces, 12 edges of equal length, 6 vertices and angles of equal size. A regular octahedron is the dual polyhedron of a cube. Irregular octahedra may have as many as 12 vertices and 18 edges. It is the three-dimensional case of the more general concept of a cross polytope. Here is an online edge length of Octahedron calculator which helps to calculate the edge length of Octahedron. Just enter the value of the surface area to calculate edge length of Octahedron.
