How much pressure is exerted on a science lab floor

The pressure at the bottom of the tube is atmospheric pressure, P bottom ≈10 5 N/m 2 and at the top the pressure is zero; therefore there is a force F up on the tube which is F=(P bottom-P top)A≈10 5 A N. But F is holding up the weight, so F=mg or 10 5 A=10 4 Ah or h≈10 m. A cancels out!
