Using the information given in the question, we can't tell.
-- ' cm² ' is not a unit of volume, so the volume of the paper clip can't be 2cm² .
-- To calculate the density of anything, we need to divide its MASS by its volume. So, even if we did know the volume of the paper clip, we still don't know its mass, so we don't have enough information to calculate its density.
Sorry.
