Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

im confused, the are witch the pressure is effecting is the are that the beam is in contact with the wall, that mean that the the force is = Q=P1/A, the the A would be 300m2/100m= L3 lets call it, and then L3 x Z, Z being the thickness of the beam in the Z direction, the same applies to P2, i think there is something missing in these solutions
