The diagram shows the main structures of the human respiratory system. The labelled alveoli (C) are spherical with an average radius of 0.10 mm. The total number of alveoli is \(4.8\times10^{8}\). Because each alveolus is highly folded, the effective internal surface area is three times the geometric surface area of a smooth sphere.\n\nCalculate the total internal surface area available for gas exchange in the lungs, expressing your answer in square metres (m\(^2\)).
