Regular Octahedron

This page provides a diagram and functioning calculator to compute the mass moment of inertia for a regular octahedron, both a solid and hollow octahedron. 
﻿
Isolid=16ms2I_{solid} = \frac{1}{6}ms^2Isolid​=61​ms2
﻿
Ihollow=110ms2I_{hollow} = \frac{1}{10}ms^2Ihollow​=101​ms2
The following are the variables for the equations...
I = the moment of inertia (﻿kg/m2
).
m = the body's mass (kg).
s = the side length of the octahedron (m).
