A real gas within a closed chamber at $\displaystyle 27^{\circ} \mathrm{C}$ undergoes the cyclic process as shown in figure. The gas obeys $\displaystyle P V^3=R T$ equation for the path $\displaystyle A$ to $\displaystyle B$. The net work done in the complete cycle is (assuming $\displaystyle R=8 \mathrm{~J} / \mathrm{mol} \mathrm{K}$ ):
