A helium balloon can just lift a load of 800 N. The skin of the balloon has a mass of 1.10 kg. What is the volume of the balloon?(the density of air is 1.29 kg/m³ and the density of helium is 0.179 kg/m³)

F(archimedes) - w(load) - w(balloon) - w(helium) = 0
p(air) * g * V - w(load) - w(balloon) - p(helium) * g * V = 0
1.29 * 9.8 * V - 800 - 1.1 * 9.8 - 0.179 * 9.8 * V = 0
V = 74.46 m^3

A helium-filled balloon, whose envelope has a mass of 0.26 kg,
is tied to a 3.6-m long, 0.053-kg string. The balloon is spherical
with a radius of 0.40 m. When released, it lifts a length
h of the string and then remains in equilibrium, as in the
figure below. Determine the value of h. Hint:
Only that part of the string above the floor contributes to the
load being supported by the balloon. (The density of air is 1.29
