The __density triangle__ is a trick that will tell which formula to use in order to find the density, mass, or volume when you have the other two.

The density triangle is a triangle that is split into three sections. ###
__Density__, which is symbolized by the letter "**D**," is in the left bottom section
__Mass__, which is symbolized by the letter "**M**," is on the top
__Volume__, which is symbolized by the letter "**V"**, is on the bottom right.

Write the letters D, M, and V in the triangle in the order that you reach each section as you go from left to right. The diagram below will show you how this is done.

__Density__, which is symbolized by the letter "**D**," is in the left bottom section__Mass__, which is symbolized by the letter "**M**," is on the top__Volume__, which is symbolized by the letter "**V"**, is on the bottom right.To use the DMV Triangle, after you have set it up, simply cover the item that you want to find and you have to formula!!! Below are a few demonstrations.

###
Start with the DMV Triangle:

To find the formula for "__Density__," cover up the "**D**" (as shown below).

This leaves the the "**M**" over the "**V**," giving you the formula "**M/V**." Therefore, the fomula is D = M/V

To find the formula for "__Volume__," cover up the "**V**" (as shown below).

This leaves the the "**M**" over the "**D**," giving you the formula "**M/D**." Therefore, the formula is V = M/D.

To find the formula for "__Mass__," cover up the "**M**" (as shown below).

This leaves the the "**D**" over the "**V**," giving you the formula "**D x V**." Therefore, the formula is M = D x V.

__Density__

__Volume__

__Mass__

**D**" over the "

**V**," giving you the formula "

**D x V**." Therefore, the formula is M = D x V.

# Why would we want to use this?

By using this trick, you never have to remember any of the actual formulas. All you have to do is remember "**DMV**." Since the

**D**__otor__

**M**__ehicles. The trick is knowing where each letter goes, but, once you have that down, each of the formulas can be seen easily, without a chance of error.__
