there is 13 edges in a heptagonal pyramid.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 14 edges, 8 vertices.
hexagonal pyramid
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)
a rectangular pyramid has a total of 8 edges
There are 7 or 9, depending on the bases.

A heptagonal based pyramid has: 8 faces 8 vertices & 14 edges
8 edges * * * * * Not necessarily. A triangular pyramid has 6 edges. A heptagonal pyramid had 14 edges and so on.
A heptagonal what? Prism, pyramid or something else?
Seven.
Heptagonal is an adjective: the answer depends on the noun that it refers to. A heptagonal pyramid, a heptagonal dipyramid or a heptagonal prism or some other heptagonal shape?
So there is some of this and some of that so there
A pyramid with a heptagonal base will have seven edges at the bottom, and seven edges around the circumference, so 14 edges in total.
Faces = 8 Edges = 14 Corners = 8
Yes. A heptagonal pyramid.
Faces: 14 Vertices: 9 Edges: 21
14. 7 for the base and 7 to meet at the top.
