aren't some of those solids, and not surfaces?

No, these are all surfaces. The ones that look like solids are actually just the surfaces of the solid. For example, the "cube" which is defined by x^6y^6z^6=1, if you wanted the whole solid, you would have to put it as x^6y^6z^6 is less than or equal to 1. Otherwise, even the point (0,0,0) doesn't belong.
