I believe that problem borders the impossible in the general case.
You can approximate the volume of an object by taking samples, but that's
inaccurate and slow.

For simple shapes like sphere and box, you can do the maths using the dimentions used.
For other
shapes, the formuas are more complex, look in your geometry and trigs school books. If
you used CSGs
operations, isosurfaces, meshes or hightfields, I doubt you can even get a decent
evaluation in most
cases.
