Truncated cube

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