Truncated cube


Truncated cube

The truncated cube, or truncated hexahedron, is an Archimedean solid. It has 6 regular octagonal faces, 8 regular triangular faces, 24 vertices and 36 edges.

Area and volume

The area "A" and the volume "V" of a truncated cube of edge length "a" are::A = 2(6+6sqrt{2}+sqrt{3})a^2 approx 32.4346644a^2:V = frac{1}{3}(21+14sqrt{2})a^3 approx 13.5996633a^3.

Cartesian coordinates

The following Cartesian coordinates define the vertices of a truncated hexahedron centered at the origin with edge length 2ξ:: (±ξ, ±1, ±1),: (±1, ±ξ, ±1),: (±1, ±1, ±ξ)where ξ = sqrt2 - 1
