The dimensions of a cinema hall are 100 m, 50 m and 18 m. How many persons can sit in the gall, if each person required 150 m³ of air?

Given,

Dimensions of cinema hall are = 100m ×50m × 18m

Where , length = 100m , breadth = 50m , height = 18 m

Each person air requirement = 150 m³

Now,

Volume of cinema hall =

So,

Number of person can sit in cinema hall =
