🤓 Based on our data, we think this question is relevant for Professor Brenner Moyer's class at NEWARK.

Solution: An ordinary gasoline can measuring 30.0 cm by 15.0 cm by 10.0 cm is evacuated with a vacuum pump. Assuming that virtually all of the air can be removed from inside the can, and that atmospheric pressure is 14.7 psi, what is the total force (in pounds) on the surface of the can?
