In this skill we will learn the relationship between density (D), mass (m), and volume (V).
Mass is "how much stuff" is inside an object, and is usually measured in g.
Volume is "how much space" an object takes up, and is usually measured in cm³.
Density is "how tightly packed" the stuff inside an object is, and is usually measured in g/cm³.
Density: D = m / V
Be sure to look at the units carefully - they are really helpful!For example, if you see a quantity is measured in g/cm³, it must be density!
