Thanks for the pointer, Makoto.  I searched the wrong documentation (where
GetMass() isn't even found).  The connection to GetCubicVolume() of the
solids is obvious once you know about it, and the MC estimation explains the
per-mil or so difference I saw with each instance.  It all makes perfect
sense, and is good enough for my application.
