1. Answer :

   • 5 is the vertices of the pyramid

   Given :

   • A pyramid with square base has 5 faces and 8 edges by euler’s formula

   To find :

   • Vertices of pyramid

   Solution :

   Given,

   • Number of faces = 5
   • Number of edges = 8

   As we know that

   • Euler’s formula = V – E + F = 2

   where , E is edges and F is faces

   》V – E + F = 2

   》V – 8 + 5 = 2

   》V – 3 = 2

   》v = 2 + 3

   》v = 5

   Hence , 5 is the vertices of the pyramid
