the once you are supposed to see, 8.
include the once there are supposed to be behind, ... ?

solomonzelman · Answer

the tip: (looking like)    /\       will have 4 edges that touch the very top corner.
and so it is for the bottom, (looking like) \/      will have 4 edges that touch the very bottom corner.

then the 4 edges around the shape (the once that are not going down or up, just around)

solomonzelman · Answer

you were likely counting just the solid lines that you can see on the attachment. But the shape itself has more as we should all agree....
