What Is Mass, Density, and Volume?

[Erwin]

Hello! I’m confused about mass, density, and volume. How are they related, and what are the formulas to calculate them?

Mass is the amount of matter in an object, measured in kilograms or grams. Volume is the space an object occupies, measured in liters or cubic meters. Density is mass divided by volume, showing how compact the matter is. It’s calculated as density = mass ÷ volume.
