Solution

Dear Student ,
Here in this case the pressure on the surface with dimension 15 cm and 20 cm is ,
Pa=20×1015×20×10-4=6666·67 N/m2
Now the pressure on the surface with dimension 20 cm and 25 cm is ,
Pb=20×1025×20×10-4=4000 N/m2
Now the pressure on the surface with dimension 15 cm and 25 cm is ,
Pc=20×1015×25×10-4=5333·33 N/m2
