A heptagonal what? Prism, pyramid or something else?
Faces: 9 Vertices: 14 Edges: 21
Faces: 14 Vertices: 9 Edges: 21
A heptagonal prism gas 21 edges.
I don't want the answer. I want to know how to find the answer for myself.
It depends on the exact shape. An octahedron is a shape with eight faces. It can be a heptagonal pyramid (8 vertices, 14 edges), or a hexagonal prism (12 vertices, 18 edges), square dipyramid (6 vertices, 12 edges) are some examples. There are more.
A heptagonal based pyramid has: 8 faces 8 vertices & 14 edges
Faces: 9 Vertices: 14 Edges: 21

It has 8 faces, 6 Vertices, and 12 edges * * * * * That is one configuration. An octahedron can also be a heptagonal pyramid which has 8 faces, 8 vertices and 14 edges.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 8 faces, 8 vertices, 14 edges

A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 14 edges, 8 vertices.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
There is no 3d shape made up of octagons. An octahedron can be one of several different shapes - but without ANY octagonal faces. For example, A hexagonal pyramid (8 faces, 18 edges, 12 vertices) A heptagonal pyramid (8 faces, 14 edges, 8 vertices) A quadrilateral dipyramid (8 faces, 12 edges, 6 vertices)
