An edge is where two faces meet.

Imagine a box containing a new mobile phone.

The left hand face of the box has 4 edges (front, back, top and bottom) and the right hand face has also 4 edges.

But there are 4 more edges where the front meets the top, the top meets the back, the back meets the bottom and the bottom meets the front.

This makes 12 edges in total.
