Explanation / Answer
weight of left piston = 1.9 * 9.8 N
diameter = 0.045 m
weight of right piston = 3 * 9.8 N
diameter = 0.12 m
pressure on left = 1.9 * 9.8 / [ phi *0.045^2 /4 ] = 11713.4544
pressure on right = 3 * 9.8 / [ phi *0.12^2 /4 ] =2600.8492
the height difference h between the two pistons h
2600.8492 + h * 700 *g= 11713.4544
h =1.32836 m
