Question

If a polyhedron have 6 vertices and 12 edges,then find its number of faces if a polyhedron have 9 vertices and 5 faces,then find its number of Edges​

Answer 1

Answer:

mark me as brain list

Step-by-step explanation:

Given Vertices (V) = 8 ,Faces (F) = 6 , Let the number of edges be E

V+F-E = 2 ( Euler's formula)

Hence 8 + 6 - E = 2

14 - E = 2

-E = -12

E = 12

Hence If a polyhedron has 6 faces and 8 vertices, then it has 12 edges
