Calculating Density: Mass and Volume Relationship

The video tutorial explains the concept of density, which is the mass of a substance per unit volume. It compares the density of polystyrene and granite, demonstrating that granite is denser. The formula for calculating density is introduced, using the Greek letter rho to represent density, mass in kilograms, and volume in cubic meters. The tutorial provides examples, including calculating the density of brown sugar, the mass of an oak tree, and the volume of water, to illustrate the application of the density formula.
