A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
9, 9 and 16
A triangular pyramid consists of a triangular base. Attached to each side of the triangular base is a triangular face and these all meet up at the apex of the pyramid. There are, therefore, 6 edges, 4 bases and 4 vertices.
a pyramid
You cannot. For example: 6 faces can be a cuboid (8 vertices and 12 edges) or it can by a triangular di-pyramid (5 vertices, 9 edges). Incidentally, a triangular di-pyramid is just two triangular pyramids stuck together at one face.
Cube: 6 faces, 12 edges and 8 vertices. Cuboid: 6 faces, 12 edges and 8 vertices. Sphere: 1 Face and no edges or vertices. Cylinder: 3 faces, 2 edges and no vertices. Cone: 2 faces, and 1 edge and vertices. Triangle Pyramid: 4 faces and vertices and 6 edges. Square Pyramid: 5 faces and vertices and 8 edges. Triangle Prism: 5 faces, 9 edges and 6 vertices. Examples, Cube: A box Cuboid: A keyboard Sphere: A ball Cylinder: Can of beans Cone: Ice-cream cone Triangle Pyramid: Bit of a tobarone bar Square Pyramid: Egyptian Pyramid Triangle Prism: Tobarone Bar
A sphere has no edges or edges but its face is globular.

A pentagonal pyramid has 6 faces. It has 10 edges and 6 vertices. It looks just like a pentagon on face and has a point at the top.

Tetrahedron or triangular pyramid.
An octagonal prism has. 10 faces. 24 edges. 16 vertices. (See image below of an octagonal prism). If placed on one of its ends, an octagonal prism has. 8 vertical faces (thus the “oct…” part of its name) plus a top and bottom face.
