A block of mass 2.0 kg occupies a volume of 0.0005 m^3. What is its density?

Density is mass per unit volume, so you divide the mass by the volume to get how tightly the material is packed. Here, density = 2.0 kg ÷ 0.0005 m^3 = 4000 kg/m^3. This is the amount of mass in each cubic meter of the block. If you try the other densities, they’d imply different volumes for the same 2 kg: 2000 kg/m^3 would need 0.001 m^3, 8000 kg/m^3 would need 0.00025 m^3, and 1000 kg/m^3 would need 0.002 m^3. The given volume leads to 4000 kg/m^3.
