Answer 5

Start from any corner. Select any face of the including corner. Trace out the four edges surrounding the face. Once you reach the starting point again move to the opposite face through the edge connecting these two faces and passing through the starting point. Now trace out the four edges on that face too. So total = 4 + 1 + 4 = 9 edges

That is the only way I know how to do it.
