How many faces, edges and vertices does a pyramid have with n sided polygon as its base?
उत्तर
In a pyramid, the number of vertices is 1 more than the number of sides of the polygon base, i.e. vertices = n + 1
Also, the number of faces is 1 more than the number of sides of the polygonal base, i.e. faces = n + 1
But the number of edges is 2 times the number of sides of the polygonal base, i.e. edges = 2n.
