How many edges does a Möbius strip have?

one

The Möbius strip is a surface with only one side and only one boundary com­po­nent (edge). A line drawn starting from the seam down the middle will meet back at the seam but at the "other side". If con­tin­ued the line will meet the starting point and will be double the length of the original strip.
