With this equation, the moments of inertia of a composite shape, which is made up of multiple elementary shapes, can be found. The moment of inertia of each individual shape about its own centroidal axis is found first; then, the parallel axis terms are added to determine the moment of inertia of the composite area.  

For composite shapes made up of smaller shapes or subparts, the moment of inertia for the entire cross-section is equivalent to the sum of the moments of inertia of the individual shapes, 1, 2 and 3, about the global N.A. in the diagram shown here.

If there are any holes or voids within the cross sections, their moment of inertia must also be calculated but subtracted from the total.
