Octagonal prism?
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 2-dimensional, an octahedron is 3-dimensional.
Octagonal prism?
the 3 dimensional shape is a octagon, because their are 8 sides.
If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.

it's still 8
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.
it's 2 dimensional
An octagon is an 8 sided 2 dimensional shape. A cylinder with the base of a hexagon (6 sided shape) would be an 8 sided 3 dimensional shape.
An octagon is a two-dimensional shape.
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.
