Rotational Inertia of Rectangular Cube in a Hoop

Click For Summary
SUMMARY

The discussion centers on the calculation of rotational inertia for a rectangular cube within a hoop. The rotational inertia of a cube with side length 's' about an axis perpendicular to one of its faces and passing through its center of mass is definitively stated as 1/6 m s². The conversation also clarifies that the rotational inertia of a compound object is the sum of the rotational inertias of its individual components. The term 'rectangular cube' is questioned, indicating a need for precise terminology in physics discussions.

i know that the equation for rotational inertia of a hoop is different than the equation for a solid cylinder, but what is the equation for a rectangular cube in a hoop?

I have no idea what that diagram is supposed to show, but the rotational inertia of a compound object is just the sum of the rotational inertias of each component. The rotational inertia of a cube of side s about an axis perpendicular to a face and passing through its center of mass is: 1/6 m s^2
 
What do you mean by the term 'rectangular cube'?
