 Hello and welcome to the session. Today I will help you with the following question. The question says, is it possible to have a polyhedron with any given number of faces? First let's discuss what a pyramid is. A pyramid is a polyhedron whose base is a polygon of any number of sides and whose lateral face is with a common vertex. It is the key idea for this question. Now let's move on to the solution. We already know that the number of sides of smallest polygon is equal to 3 that is it is a triangle. Let's have a look at the pyramid. This is a pyramid in which the base is a triangle that is the smallest polygon. Now on each edge of this base we have one lateral face, this is one lateral face, this is another lateral face and this is another lateral face. So in all we have three lateral faces and one base so total we have four faces in this polyhedron that is pyramid. So we have to make a polyhedron with smallest polygon that is triangle as the base four triangles as you have seen in the case of this pyramid. Thus we can say that it is possible to have a polyhedron with any given number of faces, the number of faces are greater than or equal to 4. Hence our final answer is possible only if the number of faces are greater than or equal to 4. So hope you enjoyed this session. Have a good day.
