If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.
Its a Octagon * * * * * No. An octagon is a shape with 8 sides. 8 faces implies a 3-dimensional object, which would have to be an octahedron.
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
An octahedron is a polyhedron with eight faces, twelve edges, and six vertices
it has : 6 faces; 12 edges; 8 corners. it is a 3D (3 dimensional) shape
Since it has 10 faces, it must be a decahedron.
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 three-dimensional platonic solid with eight faces is an octahedron.
A cube is a 3 dimensional shape with 6 faces, 12 edges and 8 vertices whereas a quadrilateral is a 2 dimensional shape with 4 sides.
Not any simply connected 3-dimensional polyhedron.
