📏 Mass is a measurement of the amount of matter an object contains, measured in kilograms.
🔲 Volume is a measurement of the space an object occupies, measured in cubic meters.
📊 Density is the ratio between an object's mass and volume.
📏 Mass and volume are properties of materials, and each material has its own specific density.
⚖️ Different objects made of the same material always have the same density, regardless of their mass and volume.
