A soda can has a surface area of 300 cm². For this problem, take atmospheric pressure to be 1.00 x 10⁵ Pa.

An empty soda can can be crushed by air molecules bouncing off it if the total inward force on the walls of the can reaches 440 N. This can be achieved by reducing the pressure inside the can. What does the pressure inside the can have to be to crush the can? Assume that the pressure outside the can is atmospheric pressure.
