A pyramid, in mathematical terms is a 3D shape with a polygonal base (with n sides) and n triangles that meet at an apex. This gives n+1 surfaces in all. n can be 3 or more.

It depends on what type of pyramid. Their is an square pyramid, a rectangular pyramid, a pentagonal pyramid, etc.
The flat surfaces on a pyramid (Geometry) are called faces. Therefore, a standard pyramid consists of four faces and a base (bottom).
The question is ambiguous since a rectangular pyramid and a rectangular prism will have different numbers of flat surfaces. There is no indication in the question which shape is intended.
A triangular pyramid is one with a triangle shaped base and triangular sides (4 sides, all of them identical), therefore it would only have 6 edges and 4 vertices There are eight edges in a triangular pyramid, and there are five vertices on a triangular pyramid. Edges are the places where two flat surfaces meet. Vertices are the places where three or more flat surfaces meet. * * * * * The sides of a triangular pyramid need not be identical.
flat surfaces on any polyhedron are called faces
