What does edge length mean? 

For example, I'm trying to picture this in my head but I don't understand. Is it a square or a cube?

"A current-carrying wire is bent into the shape of a square of edge-length 8 cm"

Thanks!

Just means the length of one side of the square shape formed by bending the wire
