All shapes that are 3-dimensional and closed are called polyhedrons. Polyhedron in greek decomposes into 'many faces.' The naming convention is to append -'hedron' to a greek prefix denoting the number of faces. Therefore any shape with nine faces will be a nonahedron.In order to factor in the faces and edges systematically would require graph theory, because they depend on what shape each of the faces is and the organization of the arrangement.Assuming:you don't want to learn graph theory, andthe polyhedron has a realitively simple geometryGoogle can help. Googling 'nonahedron' yields, among others, a polyhedron called an elongated square pyramid, which can be constructed by placing a square pyramid atop a cube (think of a house, where the roof comes to a single point). The square pyramid has 5 sides, the cube has 6, however one of each is removed when they are joined so the shape is a nonahedron(5+6-2=9). Similarly, the square pyramid has 5 vertices/8 edges and the cube has 8 vertices/12 edges with 4 edges/4 vertices shared; therefore the composite shape has 9 vertices (5+8-4=9) and 16 edges (12+8-4=16).* * * * *All that is very interesting but avoids giving the simple answer which is an octagon based pyramid.
Imagine a house's roof -- two triangles joined by lines to their matching vertices. This gives you 6 vertices and only 5 sides.
