Answer

Given:

Dimensions of hall = 100 m, 60 m and 15 m

Volume of hall = l x b x h

= 100 x 60 x 15 m3

= 90,000 m3

Let n be the number of persons.

Volume of air = Number of person x Air required by each person

⇒ 90,000 m3 = n x 150 m3

⇒ n = 90,000150\dfrac{90,000}{150}

⇒ n = 600

Hence, the number of people that can sit in the Cinema Hall is 600.
