can it be measured and weighed accurately enough to calculate its

Well, I'd expect so, since I can come up with "primitive" ways to do
it.

Volume: Fill a 5 gal bucket with water until it overflows. Let it rest
on a sensitive scale and zero the scale (see below). Take the cube
(already wet, if you like), and submerge it completely, spilling water
out of the bucket. Remove cube and re-weigh bucket. You've got to
account for some things (like the mechanism used to lower the cube,
evaporation, etc.), but you should be able to determine a very
accurate volume this way.

Mass: Weight said cube (or above bucket) on a sensitive scale. Note
this could certainly be high-tech, but it could be rather low-tech as
well: say a balance beam, where the object to be weighed is on a short
lever arm, and the predefined weights are placed at the end of a very
very long lever arm.

I'm sure there are better ways, & we've developed a lot of ways of
precisely measuring things. Mass should be too much of a problem,
volume more so, but I can't see any reason it couldn't be done.

Why?
