What is the density of the rock?

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

---

To find the density of the rock in g/cm³, change the kilograms to grams, and then divide the mass by the volume.

1.08 kg = 1080 grams   {changed kilograms to grams}

Density = mass / volume
= 1080g / 400 cm³   {divided mass by volume}
=  2.7 g/cm³   {divided}
