Calculator and formulas for calculating a truncated cube
This function calculates various properties of a truncated cube. A truncated hexahedron is created from a cube where the corners are cut off in such a way that all edges are the same length. To perform the calculation, select the property you know and enter its value. Then click on the 'Calculate' button.

Volume
\(\displaystyle V=\frac{a^3 ·(21+14* \sqrt{2})}{3}\)
\(\displaystyle a= \sqrt[3]{ \frac{3 · V }{21 + 14 ·\sqrt{2}}} \)
Surface area
\(\displaystyle S= 2 · a^2 ·(6+6· \sqrt{2} +\sqrt{3})\)
\(\displaystyle a= \sqrt{ \frac{S}{2 ·(6+6· \sqrt{2} +\sqrt{3})}} \)
Height
\(\displaystyle h=a·( 1+ \sqrt{2})\)
\(\displaystyle a= \frac{h}{1+ \sqrt{2} } \)
Outer radius
\(\displaystyle rc=\frac{a·\sqrt{7+4· \sqrt{2}}} {2} \)
\(\displaystyle a=\frac{2·rc}{\sqrt{7+4 · \sqrt{2}}} \)
Midsphere radius
\(\displaystyle rm=\frac{a·(2+ \sqrt{2})}{2}\)
\(\displaystyle a= \frac{2 ·rm}{2+ \sqrt{2} } \)
