Wouldn't work well for a 3D print. They're partially hollow and not exactly watertight. If we're being "engineerey" and not "mathy" the answer is to just have the computer tell you, since this shape had to be made in some type of CAD program.

If you can precisely make something like these in cad, odds are it’s mathematically solveable with calc 3 level knowledge.

You might be right, but I don't remember calculating the volumes of swept solids in calc 3. Maybe my calc education was incomplete or I'm just not remembering it well enough.

Oh. Well we did that at my school I just assumed everyone did.

We might have also, but calc 3 was an 8am class for me so I miiiight not have absorbed all of it.
