Yes, in my most recent best answer to one of your questions, you will see that I calculated out 60 cubic feet of helium would be enough to lift a 120 pound person.

My gut reaction - no, this is not enough helium for a human to fly.

you can calculate the force that will be lifting up (just like you'd calculate a force on an object submerged in water) and compare it to the gravitational force.

The buoyant force on the human+helim suit is due to the displaced air. Let's assume this volume is 60 cu ft plus the volume of the human, all together approx 6 m^3
It is equial to the weight of 6 m^3 of air: F= (density of air) * g * 6 m^3 = 75.8 N
(Density of air is 1.29 kg*m^3)

The weight of the an adult person is approx 700 N

75.8 << 700 no he cannot fly

You might. It depends on your weight. The upthrust of the helium must be greater than the force of gravity on your mass, which is your weight. If that is true then you will fly.

idk the lifting power of a cubic foot of helium, but if you saw the MythBusters episode when they tried to lift a 5 year old off the groud with helium balloons, it took thousands...i doubt that's possible
