Answer: 6 edges
Explanation:
What is a polyhedron? A polyhedron is a 3D shape with polygonal faces, straight edges, and sharp vertices. In other words, it is a "three-dimensional polygon."
We can use Euler's Forumla to solve since they give us the number of faces and vertices.
First, we will set the equation equal to E (edges).
F + V - E = 2
F + V - 2 = E
E = F + V - 2
Then, we will solve.
E = F + V - 2
E = 4 + 4 - 2
E = 8 - 2
E = 6
The polyhedron will have 6 edges.
