An octagonal based pyramid has 9 faces, 16 edges and 9 vertices
none
Not too sure but you may be thinking of a cube which has 6 same flat faces, 12 edges and 8 vertices
A hexagon is a plane (2-dimensional) figure with 1 face, 6 vertices and 6 sides (which may be called edges).
Cylinda is, if we may remark, very nicely shaped, with no vertices or edges.Unfortunately, however, she has been accused of having several faces.
A triangular based pyramid has 6 edges, 4 faces and 4 vertices
A triangular prism has 5 faces,9 edges and 8 vertices
An octagonal based pyramid has 9 faces, 16 edges and 9 vertices
a cuboid has 6 faces, 12 edges and 8 vertices this is a 3d cuboid incase you get mixed up
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 5 faces, 10 edges, 5 vertices
4 faces, 8 edges, and 4 vertices.
none
5 faces: 2 triangular faces, parallel to each other. 3 rectangular faces, joining the two triangles together. 6 vertices: These may be viewed as two triplets forming two triangles. 9 edges: Three edges along the boundaries of each triangle, and three more joining the corresponding vertices.

A square pyramid has 5 vertices:4 (coplanar) vertices form the square base which gives the shape its name, and the fifth at an apex (above the base).A square based pyramid has 5 vertices, 8 edges and 5 faces
