A quantity of a substance in a closed system is made to undergo a reversibel process from an initial volume of `3 m^(3)` and initial pressure `10^(5) N//m^(2)` to a final volume of `5m^(3)`. If the pressure is proportional to the squre of the volume `(i.e,P=AV^(2))`, the work done by the substance will be
A. `3.6xx10^(2)J`
B. `7.4xx10^(3)J`
C. `2.2xx10^(4)J`
D. `3.6xx10^(5)J`
