8. There are 7 vertices on the heptagon, and 1 vertex for the top of the pyramid.
A heptagonal pyramid has eight vertices.
A heptagonal what? Prism, pyramid or something else?
Faces: 14 Vertices: 9 Edges: 21
It will have 8 faces, 14 edges and 8 vertices
There are many such solids: A heptagonal pyramid A cuboid (or rectangular prism) A hexagonal dipyramid A pentagonal pyramid with a 2-vertex shape on the other side etc.
If the pyramid has a triangular sides then truncate each vertex (cut off a small pyramid shape from the vertices).If the pyramid has a quadrilateral base then truncate 3 vertices.If the pyramid has a pentagonal base then truncate 2 vertices.If the pyramid has a hexagonal base then truncate 1 vertex.If the pyramid has a heptagonal base then it is already an octahedron.If the pyramid has an base with 8 or more vertices then slice off the section formed by joining the apex and two vertices from the base which are six apart. This makes the base heptagonal and therefore the shape is an octahedron.
A heptagonal based pyramid has: 8 faces 8 vertices & 14 edges
A heptagonal what? Prism, pyramid or something else?
Heptagonal pyramid * * * * * No. A heptagonal pyramid has 8 vertices. You need a hexagonal pyramid or a pentagonal dipyramid for 7 vertices. Or, in 2d, a heptagon.
Faces: 14 Vertices: 9 Edges: 21
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.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 8 faces, 8 vertices, 14 edges
there is 13 edges in a heptagonal pyramid.
14 vertices
It has 14 vertices
Heptagonal prism * * * * * No, a heptagonal prism has 9 faces. The correct answer is a hexagonal pyramid.
It will have 8 faces, 14 edges and 8 vertices
