  1. A handy little way of dealing with the ‘density equation’, You don’t have to memorize it since it’s on the first page of the reference tables. Just put M over V and divide. No problem. But what if you’re given D and M and asked to solve for V? What If you’re given D and V and asked to solve for M? What now? EASY!Just remember “Mountains over Deserts and Valleys”

  2. Mountains up here and……….. Deserts and valleys down here.

  3. Now draw a triangle……… And draw these lines Insert M for mountains, D for deserts and V for valleys M V D

  4. All you have to do is COVER whichever term you want to solve for. For instance, if you need to solve for mass, just cover the ‘M’. You’re left with DV so M = DV M V D

  5. To solve for volume, just cover the “V”. That leaves M/D so V = M ÷ D M V D

  6. And of course density, ‘D’ equals M ÷ V M V D

  7. So just remember……… Mountains over deserts and valleys And then check your math……….twice! M V D
