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::$A = 2\left(6+6sqrt\left\{2\right\}+sqrt\left\{3\right\}\right)a^2 approx 32.4346644a^2$:$V = frac\left\{1\right\}\left\{3\right\}\left(21+14sqrt\left\{2\right\}\right)a^3 approx 13.5996633a^3.$

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 = $sqrt2 - 1$
