Answer:
A prism is a polyhedron which has two congruent bases and a pyramid has only one base
A cylinder has two circular bases such that it's sides are curved not flat.
A cone has only one circular base with one vertex.
Explanation:
A prism and a prism are three dimensional figures with sides and faces as polygons.
A prism is a polyhedron which has two congruent bases and a pyramid has only one base.
The base is not of the form of circle or oval.The sides and bases are always polygons.
The base can be square , triangle , rectangle etc.
Cone and cylinder are also three dimensional figures with some differences.
A cylinder has two circular bases such that it's sides are curved not flat.
A cone has only one circular base with one vertex.
