20 edges, 11 vertices (corners) and 11 faces.
A triangular based pyramid is usually called a tetrahedron and it has 4 faces, 6 edges and 4 corners (usually called vertices)
5 faces 9 edges 6 corners
An octagonal pyramid has 9 faces and 14 edges. The base of the pyramid is an octagon with 8 faces, and the pyramid itself has an additional triangular face. The edges consist of the edges of the octagon base and the edges connecting the base to the apex of the pyramid.
By "corners", do you mean vertices or edges?
A pyramid has 5 faces, 5 corners and 8 edges corners and faces are always the same
Faces = 8 Edges = 14 Corners = 8
A triangular-based pyramid has 4 corners, 4 faces and 6 edges.
4 corners 6 edges 4 faces
5 corners, 8 edges and 5 faces
A pyramid with 8 edges has 5 faces, 5 corners and (of course) 8 edges.
faces = 5 edges = 8 corners (vertices) = 5
5 faces 8 edges 5 corners (vertexes) * * * * * Wrong! The answer given above is for a SQUARE based pyramid. A triangle based pyramid, or a tetrahedron, has 4 faces, 6 edges and 4 corners (vertices).
A pyramid with a rectangular (square) base has:Eight edges,Five vertexes (corners)Five faces
20 edges, 11 vertices (corners) and 11 faces.
A square-based pyramid has:5 Faces (4 triangles and 1 square)5 Vertices (Corners)8 Edges
