Pascal's law

Please calculate according to Pascal's law. Krupp's machines were known for their large size. In 1861, a blacksmith's steam hydraulic press was put into operation in Essen. What was the cross-sectional area of the larger piston if a compressive force of 150 kN could develop by applying a force of 200N to a small piston with a capacity of 40 cm2?

Correct result:

S2 =  30000 cm2


p1=p2 F1/S1=F2/S2 F1=200 N S1=40 cm2 F2=150000 N  S2=F2F1 S1=150000200 40=30000 cm2
