Objective One:

Objective 1:
1.  Mass is more important for many reasons.  One reason, which is the main one, is that if I were to weigh myself on Mars I would have a differet weight than I would on Earth.  This shows that the weight of an object can change but the mass is always the same.  Just like my mass wouldn't change even if I were on Mars.            http://wiki.answers.com/Q/Why_is_mass_more_useful_than_weight_for_measuring_matter
2. the volume is 619.65cm3 (the three is supposed to be very small and on the top but I don't know how to do that)
3.  The measurement of density is g/cm3 (same thing up there with the three being small and on the top)
4.  D=mass over volume
5.  V=L*W*H (* means times)
