Density calculation: mass 3.0 kg and volume 0.6 m^3.

Density calculation: mass 3.0 kg and volume 0.6 m^3.

• A. 5.0 kg/m^3
• B. 3.0 kg/m^3
• C. 4.0 kg/m^3
• D. 6.0 kg/m^3

Answer: (A)

Density is mass per unit volume. So you divide the mass by the volume to get how dense the object is. With a mass of 3.0 kg in a volume of 0.60 m^3, the calculation is 3.0 ÷ 0.60 = 5.0, giving 5.0 kg/m^3. The units come from kilograms per cubic metre. If you try other densities, you’d get different volumes for the same mass, for example 3.0 kg at 3.0 kg/m^3 would take 1.0 m^3, at 4.0 kg/m^3 it would be 0.75 m^3, and at 6.0 kg/m^3 it would be 0.50 m^3.
