WebMar 15, 2024 · Total weight of balloons = Nw. Buoyancy force = weight of air displaced and this must be greater than the weight of the helium + the weight of balloons + person's weight. Volume of a balloon V = 4/3πr 3 = 4/3 x 3.1416 x (15 x 10 -2) 3 = 1.414 x 10 -2 m 3. So write the equation: NVρ a > NVρ h + Nw + W p. truro town offices
