The radius of a helium balloon required to lift a total weight of 180 kg, including the balloon's own weight, can be estimated using the formula F = ρgV, where ρ is the density of helium (0.179 kg/m³) and g is the acceleration due to gravity. The calculated radius is approximately 3.22 meters. However, it is crucial to consider the density of the surrounding air, as this affects buoyancy. Without accounting for air density, the calculation is incomplete, as a balloon in a vacuum would not achieve lift regardless of its size.
