2. If a polyhedron has 19 vertices and 13 faces, how many edges does it have?

Margaret [11]

Answer:

30 Edges.

Step-by-step explanation:

Euler's formula tells us that $V-E+F=2$ (Vertices - edges + faces = 2).

Plug the numbers in:

$19-E+13=2$

Solve:

$32-E=2$

$32=2+E$

$30=E$

Therefore, there are 30 edges.
