moment of inertia

[vscid]

I am trying to find out how to calculate the
mass moment of inertia of an assembly.
I have basically a ring 7 inch ID,11 Inch OD
and 1 inch thick.

On this ring I have several rectangular boxes mounted
of various sizes around its periphery (screwed.)
This ring will rotate about its axis along with those
boxes of different sizes.
How do I calculate the inertia of the assembly?

please help.

Here you go. BTW, if this is homework or coursework, it can be moved to the Homework Help forums.

This is a HW/Schoolwork-type question. So it belongs in the HW/Coursework forum even if it isn't a homework assignment.
