If a solid shape has 12 faces and 20 vertices, then the number of edges in this solid is ______.
Solution:-
If a solid shape has 12 faces and 20 vertices, then the number of edges in this solid is 30.
We have,
Euler’s formula for any polyhedron is, F + V – E = 2
Given, F = 12, V = 20
Where, face (F) = 12, Vertex (V) = 20, Edge (E) =?
Then,
12 + 20 – E = 2
32 – E = 2
32 – 2 = E
Edges (E) = 30
