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