A triangular based pyramid has 4 flat faces, 6 edges and 4 vertices.
A pyramid has a total of ( n + 1 ) plane surfaces, where ( n ) is the number of triangular faces. For example, a square pyramid has a square base (1 surface) and four triangular faces, resulting in a total of 5 plane surfaces. The specific number can vary depending on the shape of the base; for instance, a triangular pyramid (tetrahedron) has 4 surfaces in total.

a pyramid with a triangular base has 4 faces. a pyramid with a square base has 5 faces.
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.
4 triangle surfaces
not a pyramid!! well a triangular won't but still pyramids have 4 flat surfaces.
A pyramid has a combination of flat and curved surfaces, but it typically consists of flat surfaces only. Specifically, a pyramid has a base that is a polygon (flat surface) and triangular faces that connect the base to a single apex, all of which are flat. Therefore, a standard pyramid has no curved surfaces. The total number of surfaces depends on the number of sides of the base polygon; for example, a square pyramid has five flat surfaces (one base and four triangular faces).
triangular pyramid
A square base, and four triangular shaped sides equals five flat surfaces.
