pardon my ignorance but what the fuck is a “cross product” or a “dot product”? I assumed at first this was multiplication, but then I saw the dot and realized this isn’t anything I’ve ever been taught

that’s fine, and thanks for the links! I just don’t quite agree that this is suprisingly simple mathematics :P

yeah it’s “surprisingly simple” in the sense that there’s a well-defined algorithm to do it. a computer can do it easily, with very little time/effort. anyways, you don’t need to think about every problem specifically. “now i got this parallelepiped, how do i calculate the volume?” you can just use the same formula every time.
