What is Density?
Density is the measure of how tightly packed mass is within a given unit volume of a substance.
Formula & Step-by-Step Calculation
ρ = m / V
Mass divided by volume.
Worked Step-by-Step Examples
Example 1
1000 kg occupying 1 cubic meter
Solution: 1,000 kg/m³ (1 g/cm³)
• 1000 / 1 = 1000 kg/m³
Common Real-World & Academic Use Cases

Frequently Asked Questions
Q: Why does ice float on water?
Because liquid water expands when freezing, giving ice a lower density (~917 kg/m³) than liquid water (1000 kg/m³).
