0 faces, it's 2 dimensional 4 sides (2 dimensional) 4 vertexes
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. There are 6 of them. There are 12 edges.
Sides and faces are the same thing, and an octahedron has eight.

A square based pyramid has 5 vertices, 5 faces and 8 edges
An octahedron has eight faces - by definition.
An octahedron has 8 sides.
32 sides

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
