Solution

$The dimensions of a cinema hall are 100 m \times 50 m \times 18 m . i . e ., volume of air in the cinema hall = 100 \times 50 \times 18 = 90000 m^{3} It is given that each person requires 150 m^{3} of air . ∴ The number of persons that can sit in the cinema hall = \frac{volume of air in hall}{volume of air required by 1 person} = \frac{90000}{150} = 600$
