An octahedron is an eight sided polyhedron. It has eight sides or faces, 12 edges, and six vertexes. Please see the Related Link below for more information and a picture.
0 faces, it's 2 dimensional 4 sides (2 dimensional) 4 vertexes
An octahedron has eight triangular faces. It is a type of polyhedron characterized by its two square pyramids joined at their bases. In addition to its eight faces, an octahedron has six vertices and twelve edges.
An octahedron has 8 sides.
A "dodeca" is a prefix: it is not a shape. An octahedron has eight faces.
hexagonal prism In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces. https://en.wikipedia.org/wiki/Hexagonal_prism#/media/File:Hexagonal_prism.png
Sides and faces are the same thing, and an octahedron has eight.

Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.
if you mean how many edges then it's 12
