It is a triangular prism that has 5 faces. 6 vertices and 9 edges
5 vertexes, 4 faces, and 8 edges
A tetrahedron has four vertexes and four faces and six edges.
Slender is not a polyhedron.
A hexagonal pyramid has 12 edges, 7 vertices and 7 faces.
It is a triangular prism that has 5 faces. 6 vertices and 9 edges
5 vertexes, 4 faces, and 8 edges
Edges: 15 Faces: 7 Vertices: 10 Vertexes: None, since there is no such word!
A quadrilateral based dipyramid.
Faces: 2 circular, 1 curved rectangular. Vertices (not vertexes!): None Edges: 2 circular.
Vertices = 12 Edges = 18 Faces = 8
A tetrahedron has four vertexes and four faces and six edges.
Yes. to add to that a vertex must be connected to at least 3 edges to be 3d, an edge is always connected to 2 vertexes, so the closest the two can ever be is vetexes x 3 = edges x 2, but when working with any platonic solid you can follow this: vertexes x (faces / vertexes) x [edges on one side] = edges x 2 or vertexes x [faces meeting at one vertex] = edges x 2 when working with any other polyhedron [vertexes with x amount of faces] x (x) + [vertexes with y amount of faces] x (y) ...{and so on} = edges x 2
Slender is not a polyhedron.
A hexagonal pyramid has 12 edges, 7 vertices and 7 faces.
A triangular dipyramid - two triangular pyramids stuck together.
According to the Euler characteristic for polyhedra, V + F = E + 2 where V = Vertices (not vertexes), F = Faces and E = Edges. So F = 12
