.✪ A pyramid is a polyhedron whose base is a polygons of any number of sides and whose lateral faces are triangle , having a common vertex called vertex of the pyramid .

✪ According to Euler's formula for any polyhedron,

F+V-E=2

where,

F= Number of faces

V= Number of vertics

E= Number of Edgesl
