Gold has a density of 19.3 g/cc.

The density of a substance is defined as the mass of a unit volume of the same. If a substance has a density of X g/cc, 1 cc of the substance has a mass of X g.

Density = Mass/Volume

Given the density(D), the volume (V) of a substance with mass M is V = M/D

For gold with density 19.3 g/cc, the volume of gold with mass 45.6 kg is (45.6*1000)/19.3 ~~ 2362.69 cc

A block of gold with an approximate volume 2362.69 cc has a mass of 45.6 kg
