The measurement of volume depends on your definition of volume.

  Is volume the space enclosed by the surface?
  If so, the volume of a sphere should be larger than the volume of a
difference of a sphere and a smaller sphere.

  Is it the space enclosed by the outer contiguous surface?
  If so, how do you calculate the volume of this kind of object:

difference
{ box { -1,1 }
  sphere { 0, 1.1 }
}

(and suppose the same situation with more complex objects than a box and a
sphere, eg. a lathe and an isosurface.)

  Is it the space enclosed by the visible part of the outer surface?
  Something else?
