An ideal gas undergoes a cyclic transformation starting from the point A and coming back to the same point by tracing the path $\displaystyle \mathrm{A} \rightarrow \mathrm{B} \rightarrow \mathrm{C} \rightarrow \mathrm{A}$ as shown in the diagram above. The total work done in the process is $\displaystyle \_\_\_\_$J.
