Create equations in two or more variables, graph them, and label axes/scales appropriately.
Define variables and write a formula with units
Problem
Write the density formula using \(D\) for density, \(m\) for mass, and \(V\) for volume. State the units of each quantity when mass is measured in \(\text{grams}\) and volume in \(\text{cubic}~\text{centimeters}\).
Big Picture
What this problem is really about
This task is really about building a formula whose units make sense. We’ll define density, mass, and volume with their units, use the word per to decide that the relationship is a quotient, and place the quantities so the units reduce to grams per cubic centimeter. A dimensional check will confirm both the operation and the variable roles.
