anzhelika [568]

432 in²

A block of copper weighs 2160g and has a volume of 240cm3. what is the density of the copper?
densk [106]
The unit of density [kgm^-3] displays the formula.
So density=mass/volume.

Convert 2160g into kilograms [2160/1000=2.160kg]
Convert volume of 240cm^3 into m^3
100cm=1m
100x100x100=1000000cm^3=1m^3
240/1000000=[2.4x10^-4]

Final calculation
2.160/2.4x10^-4=9000

Answer: 9000kgm^-3
