P1 = P2 by Pascal's Law (the pressure in a fluid in a closed container is transmitted equally to all parts of the container)
F1 = P1 A1 the force on the smaller piston (since P = F / A)
P1 = F1 / A1 = F2 / A2 by Pascal's Law
F1 = F2 * (A1 / A2)
F1 = 1152 N * (6 cm^2 / 576 cm^2) = 12 N
The assumption must be the hydraulic machine must be a closed
container so that Pascal's Law is applicable.
