An 8-faced polyhedron, also known as an octahedron, is a three-dimensional shape composed of eight triangular faces. It has six vertices and twelve edges. The most common type of octahedron is the regular octahedron, where all faces, edges, and angles are congruent. Octahedra are found in various applications, including crystallography and geometry.
An eight-faced 3D shape is called an octahedron. Any 3D shape (polyhedron) ends in -hedron, just like any 2D shape (polygon) ends in -gon, and octa- means 8.
A pentahedron.
A tetradecachedron is a polyhedron, also known as a 14-sided polyhedron or 14-faced polyhedron. It is a convex solid with 14 faces, 24 edges, and 14 vertices. The term "tetradecachedron" can refer to any 14-faced polyhedron, not necessarily a specific shape.
The answer is a polyhedron

A polyhedron is any multi-faced solid. In order to know how many pairs, you need to know how many total faces.
