We need to calculate the density of the bar of gold, using the following formula:

$\text{density}=(mass)/(volume).$

The units of density must be in kg/m^3 or g/cm^3. We can do the conversion from kg to g. Remember that 1 kg equals 1000 g:

$12.4kg\cdot(1000g)/(1kg)=12400g\text{.}$

Now, we can apply the formula using the last data:

$\begin{gathered} density=(12400g)/(3cm^3) \\ \text{density}=4133.33\text{ }(g)/(cm^3) \end{gathered}$

Let's see how would be the density in kg/m^3, remembering that 1 m^3 equal 1000000 cm^3:
