Working with pressure to calculate the force required to pull a lid off of an airless box.

An airtight box has a removable lid of area 1.3 * 10^-2 m^2 and negligible weight. The box is taken up a mountain where the air pressure outside the box is 0.85 * 10^5 Pa. The inside of the box is completely evacuated. What is the magnitude of the force required to pull the lid off the box?
