No. Every solid shape has at least one face. The closest you will get is a sphere, which has no edges or vertices, but it still has a face.
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?
the vertices are the corners to the shape, so you count the corners to whatever shape.
It is a square based pyramid which has 5 faces, 8 edges and 5 vertices
tricontatetrahedron
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
FacesE.g. Faces of a cube
There is not a polyhedron with the given number of faces, edges and vertices.
The solid where two faces meet is called a "polyhedron." A polyhedron is a three-dimensional shape that consists of flat polygonal faces, straight edges, and vertices. Each point where two faces come together is called an edge, and the points where edges meet are called vertices. Examples of polyhedra include cubes, pyramids, and tetrahedra.
then it's a - Dodecahedron
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
An octahedron is a polyhedron with eight faces, twelve edges, and six vertices
There is no 3-d shape with 4 and 1 = 5 triangular faces.
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?
It is a cube or a cuboid which also has 12 edges and 8 vertices
Triangular prism
A parallelepiped, of which a cube is a special case.
