The shape that can slide and roll, stack and roll, and has no vertices is a cylinder. Cylinders have curved surfaces that allow them to roll smoothly, and they can stack on top of each other without any sharp edges. Their continuous surface and circular bases provide stability when stacked.

Slide.
both
A dice can roll but cannot slide. Rolling involves rotating around an axis while moving forward, typically on a flat surface. Sliding, on the other hand, involves moving without rotation, which is not possible for a dice due to its shape and lack of flat sides that would allow for smooth sliding.
I think both
A cylinder
A pyramid will not roll and you cannot stack objects on top.
No
A heptagon based prism has 8 vertices and it can roll.
Cube
The square based pyramid does not stack or roll.

A cylinder?
no
Slide.
A square, honey. It can slide on its flat surfaces, but it ain't gonna be rolling anywhere with those sharp corners. So, if you're looking for a shape that's all about sliding and not about rolling, go square or go home.
