Feb 4, 2017 at 11:18 comment added greybeard Point containment will not solve the problem: Picture $p$ a triangular prism with one side of ("Platonic") $t$ (slightly smaller, inside,) parallel and near to one of the triangular faces of $p$. Now subtract from $p$ a "needle tetrahedron" from the middle of that face to near one of the vertices "in the opposite face": None of $t$'s vertices is outside $p$, none of $p$'s vertices is inside $t$, yet $t$ is not inside $p$.
