A polyhedron has 6 faces and 8 vertices. how many edges does it have?

12 Edges.

hope you rate me well

12

Step-by-step explanation:

Euler's formula for polyhedra states

F + V - E = 2

where F is faces, V is vertices and E is edges

Here F = 6, V = 8, thus

6 + 8 - E = 2, that is

14 - E = 2 (subtract 14 from both sides)

- E = - 12 (multiply both sides by - 1)

E = 12 ← number of edges
