In geometry, the truncated cube, or truncated hexahedron, is an Archimedean solid. It has 14 regular faces (6 octagonal and 8 triangular), 36 edges, and 24 vertices.
If the truncated cube has unit edge length, its dual triakis octahedron has edges of lengths 2 and .

The area A and the volume V of a truncated cube of edge length a are:
The following Cartesian coordinates define the vertices of a truncated hexahedron centered at the origin with edge length 2ξ:
where ξ =
The truncated cube can be seen as a cube with its corners truncated, as shown in this truncation sequence:

It shares the vertex arrangement with three nonconvex uniform polyhedra:

A cube can be alternately truncated producing tetrahedral symmetry, with 6 hexagonal faces, and 4 triangles at the truncated vertices.
