Lift of balloon
- The volume of a sphere is 4/3 * pi * r^3, where r is the radius of the balloon.
- One cubic foot of helium will lift about 28.2 grams, so multiply the volume of the balloon by 28.2.
- Divide by 448 -- the number of grams in a pound -- to determine the number of pounds it can lift.
(4/3) * pi * (r^3) * 28.2 = lift in grams ((4/3) * pi * (r^3) * 28.2) / 448 = lift in pounds
