Gold metal has fcc structure. The space filling model of a unit cell is shown below. If all the octahedral voids are occupied by atoms which is ideal to fill all octahedral voids without distorting it then find the packing fraction of this crystal. $\left[\pi {\left(\frac{\sqrt{2}-1}{2\sqrt{2}}\right)}^3=0.012\right]$
