An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. In most cases there will be no parallel faces but there can be four pairs of parallel faces.
a octahedron has 8 faces
A truncated octahedron has 14 faces.
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!
An octahedron can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons,
Sides and faces are the same thing, and an octahedron has eight.
Not necessarily. A heptagon-based pyramid is an octahedron and it has no parallel faces.
An octahedron has eight faces - by definition.
In geometry, an octahedron is a polyhedron with eightfaces.
An octahedron has eight bases/faces.
