If the density of pure copper is 8.89g/cm3 (at 20•c), calculate the volume of a copper brick with a mass of 4.5kg

The volume of a substance can directly be calculated by the ratio of mass and density. That is:

volume = mass / density

Since the mass is 4.5 kg or 4500 grams, therefore:

volume = 4500 g / (8.89 g / cm^3)

volume = 506.19 cm^3
