Final answer:
The length of a paper clip can be measured in millimeters (mm). So, to calculate the length of the paper clip, you need to determine the total length of the wire used to make it.
Step-by-step explanation:
The length of a paper clip can be measured using the unit of measurement called millimeters (mm).
In this case, the diameter of the wire used to make the paper clip is given as 1.20 mm.
So, to calculate the length of the paper clip, you need to determine the total length of the wire used to make it.
