9. Can a polyhedron have 10 faces, 20 edges and 15 vertices.

Answer»

no it cannot haveits not possible

sorry wrongly posted

yesFormula isFace+ Vertices= Edge+2SOLVE: Face=10 ,Vertices=15 = Edge=20+2

next is10+15=20+225=22means : 25 is unequal to 22.

next is 10+15=20+225=22means : 25 is unequal to 22

we will use Euler's formula10 +15 = 20+225=22unequal
