A cube of edge 2cm and mass 10g is placed on the surface of a table. What is the pressure exerted by the cube on the table.

pressure=force/area=.01kg*9.8N/kg /.02^2 in Newtons.
Newtons/m^2 = Pascals
Prf Damon is correct. Pressure is in Pascals, or N/m^2. I still had you last question in my mind.
Pressure(P) =F/A,F=mg & 2cm = 0.02m (converting to MKS) so P=mg/a .Thus F=10g * 9.8m/s2 = 98 N P=F/A= 98N/0.02m =1.96 N/M2
