A certain heat engine performs a cycle described by the curve A$$B$$C$$A in the p$-$V diagram shown in the figure. The segments between the designated points are all straight. The values of the pressures and volumes at the designated points are:

VA $=0\mathrm{.}6110-3$ m$3$ VB $=3\mathrm{.}910-3$ m$3$ pA $=2\mathrm{.}94106$ Pa pB $=2\mathrm{.}32106$ Pa pC $=1\mathrm{.}34106$ Pa

Calculate the net work output of the heat engine, in joules, over a single cycle of operation.
