Take a handful of sand. Turn your first perpendicular to the ground and let it fall slowly. What shape does it form? It's one of the most stable shapes you can make.

A cone?

A pyramid is just a cone with a square base.

A cone is just a pyramid whose base has infinite sides

No, a cone can have any flat shape as its base, wherefor a pyramid - which only has four sides - is also a cone.

By definition, a pyramid can have any polygon as a base, not just a square. A cone can ONLY have a circle as a base.

I say Pyramids ⊂ Cones. You say Cones ⊂ Pyramids. Therefore Cones = Pyramids.
