Adding to what Kittenono said, an octagon is a two dimensional shape which only has length and width. A polyhedron is 3 dimensional which has length, width and height.
An octagon is a 2 dimensional object, not a 3 dimensional object. As such, it has 1 face, 8 corners, and 8 angles.
An octagon is a two-dimensional shape.
If it's a polygon (2 dimensional) then an octagon. If it's a polyhedron (3 dimensional) then a rectangular prism (or a cube).
An octagon is a 2 dimensional shaped 8 sided polygon
If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.
An octagon is 2-dimensional, an octahedron is 3-dimensional.
For a plain 2-dimensional figure it is an OCTAGON. For a 3-dimensional object it is an OCTAHEDRON.
the 3 dimensional shape is a octagon, because their are 8 sides.
A 3-dimensional shape with eight sides is an octahedron. If you would refer to a 3-dimensional octagon, just call it that, people will understand what you mean. Or maybe you mean an octagonal prism. That's an octagon, except it is extended into the third dimension by stretching it, so it has an octagonal base but the other sides are triangles all connecting at one point above the octagon.

it's still 8
A 2-Dimensional shape with 8 sides is called an Octagon.
it's 2 dimensional
An octagon is a two-dimensional shape.
