Moment of inertia of body depends upon

What are the factors on which moment of inertia of a body depend ?

The moment of inertia of a rigid body is not unique , about a given axis. The moment of inertia of a rigid depends on axis about which it has to be calculated.

The moment of inertia of rigid body depends only on the mass of the body, its shape and size. Moment of inertia I = MR^2 where M is the mass of the body and R is the radius vector.
