Density is found by taking the mass and dividing by the volume.

Since we are dealing with a cube, it is easy to find the volume. Volume of a cube is s^3, where "s" is the side length. So we take 3 cm to the power of 3, or 3^3. =27

Now we just take the mass, 12g, and divide by the volume, 27 cm^3.

Density = 12/27 = 4/9. Don't forget the units!!!

4 g ________ 9 cm^3

Please let me know if you need any clarification. I'm always happy to answer your questions.
