Wait... is this the food cube? but then topology would only differentiate four kinds:
- the one sided (equivalent to the taco, hotdog, and bowl)
- two sided (the sandwich, hamburger, I'll throw lasagna here anyway)
- the open ended tube (vietnamese eggroll, donut, bagel)
- the entirely enclosed cube (wontons, empanadas, ravioli, pierogi, sausages. also burritos and eggrolls)
