Prism and Pyramid

Guess the polyhedron. I have 6 flat faces. Some are rectangles. I have 12 edges and 8 vertices.

• Rectangular prism/cuboid

• cube

• Triangular pyramid

• Square pyramid

What is the main difference between Prisms and Pyramids?

• A prism has 2 bases and a pyramid has 1 base.

• A prism has to have all 90 degree sides and a pyramid doesn't

• A prism must have a least one curved line and a pyramid doesn't

• A prism must be 3-d but a pyramid shouldn't
