Find the density in grams per cubic centimeter

Jeremy wants to know the density of a rock in grams per cubic centimeter.  The rock has a mass of 1.08 kilograms and a 
volume of 400 cubic centimeters.  What is the density of the rock in grams per cubic centimeter?  (g/cm³)

---

​Convert the mass from kilograms to grams, then divide the mass by the cubic centimeters to find g/cm³.

1.08 kg x 1000
= 1080 grams  {there are 1000 grams in 1 kilogram}

 1080 g
----------  {divided grams by cm³}
400 cm³

=  2.7 g/cm³   {divided}
