Question

Find the number of vertices in a polyhedron which has 30 edges and 12 faces .​

Answer 1

Step-by-step explanation:

For any polyhedron, F + V – E = 2 Here, F = 12, V = ?, E = 30 Using above formula, 12 + V – 30 = 2 V – 18 = 2 V = 2 + 18 V = 20Read more on Sarthaks.com - https://www.sarthaks.com/851972/find-the-number-of-vertices-in-a-polyhedron-which-has-30-edges-and-12-faces

Answer 2

Answer:

so know that

E+2=F+V

SO,

30+2=12+V

V=32-12

V=20
