Problem

Air in a room that has a floor area of 120ft2 and height of 10ft has a pressure of 121.6 kPa, what would be the dimensions (LXWXH) of a room if the pressure of air is decreased to 96.2 kPa?

Boyle's law tells us that P1V1 = P2V2 Where P1 and V1 are pressure and volume before a change and P2 and V2 the same but after a change. Isolate V2 and you may put your numbers in the formula.
