The bottom of a box has a surface area of 25.0 cm 2 . The mass of the box is 34.0 kilograms. Acceleration due to gravity at sea
Viktor [21]
Pressure given by: 
Pressure=(force)/(area)
Force=Mass*gravitational pull
Mass=34Kg
gravity=9.80

so,
force=34*9.8=333.2
thus;
pressure=333.2/25=13.328=13.3 N/cm^2

Hope this helped :)
