    Jashandeep Gill Gammellos Chemistry Density is one of the fundamental principles of physics. Density is the reason why a plank of wood floats on water while a piece of metal several times smaller will sink. Density of an object is measured in g/cm³ or g/cc. The equation is D=M/V‚ D being the density of the object‚ M being the mass of the object‚ and V being the volume of the object. Mass is the space an object takes up. It is the amount of matter present in an object. Mass is measured using
