An octagonal pyramid has 9 faces, 9 vertices, 16 edges.

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.

no numbers have the same number of edges and vertices

A triangular dipyramid (two tetrahedrons or triangular pyramids stuck together) has 9 edges and 5 vertices. A parallelepiped (including cuboid) has 12 edges and 8 vertices

for any prism , number of ___ + number of vertices = number of edges + ___

An octagonal pyramid has 9 faces, 9 vertices, 16 edges.

Pentagonal pyramids have six faces, ten edges, and six vertices. One of the faces is a pentagonal base, the rest are triangular.

Rectangular pyramids

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.

Faces = 4 Edges = 6 Vertices = 4 The shape is also known as a tetrahedron.

If you add the vertices and Faces and subtract 2 from that number you get the number of edges. Vertices+Faces=Edges+2
