Steam at a constant absolute pressure of 20atm is admitted to the cylinder of an engine. The length of thepiston stroke is 60 cm and its diameter is 20 cm. How much work injoules does the steam perform during one full stroke of the piston?

What I did was convert atm to dynes/cm^{^2} and thencalculated the area. I determined the force from F=pA which I got636.5 J. The problem is, the text gives 636.5 J as the answer forthe work done. I still have not calculated in the length of thepiston??? I am clueless.
