**drwls**, Friday, February 22, 2008 at 9:46amYou are dividing density by volume instead of multiplying. BobPursley gave your the correct formula to use.

**Damon**, Friday, February 22, 2008 at 4:55pmcheck your units

2.70 g/cm^3 * 126.5 cm^3

units are

g cm^3/cm^3

the cm^3 cancel

and you are left with g, grams

If you do it upside down somehow, you will end up with cm^6 which you know right off is wrong.
