Density Triangle

The Density Triangle is a great memory trick that can help you to calculate density, mass, or volume if you know two of the three variables.

For each calculation, simply place your finger over the variable you need to calculate. For example, if you are given the density and mass, and need to calculate the volume, simply place your finger over the "V" in the triangle. Then, look at the arrangement of the other two variables (M and D). Notice that the M is over the D. This tells you that you need to divide mass by volume.
