ρ = m / V, in kg/m³.
An object floats in a fluid if its density is lower than the fluid's — a steel ship floats not because steel is light, but because its overall shape displaces enough water to make its effective density lower than water's.
Water sits at almost exactly 1,000 kg/m³, which makes it a handy mental benchmark — most everyday liquids and many solids fall within an order of magnitude of that number.
Density (kg/m³)
2,500
ρ = m / V
What you entered
Density: ρ = m ÷ V
5 ÷ 0.002= 2500Result
Density (kg/m³): 2,500
5kg packed into 0.002m³ gives a density of 2,500 kg/m³ — water is 1000 kg/m³ for comparison.
