• Zero. The force on any face of the box is equal to the force on the opposite face. Otherwise, the box would move.
    • 1!Telly
      I'm afraid the force isn't zero. The 'work done' by that force is zero.
  • Pressure is defined as force per unit cross-sectional area. P = F/A therefore F= P*A now, cross-sectional area = 20*20 = 400 msq(assuming the box is a cube of length 20m) Therefore, Force = 12*400 = 4800 N
