Question

The dimensions of a cinema hall are 100 m, 50 m and 18 m. How many persons can sit in the hall, if each person requires 150 `m^3` of air?

Answer 1

Given that
Volume of cinema hall = `100xx50xx18m^3`
Volume air required by each person = `150m^3`
Number of person who can sit in the hall

`= "volume of cinema hall"/"volume of air req each person"`

`=(100xx50xx18m^2)/(150m^3)=600           [∴v=lxxbxxh]`

∴number of person who can sit in the hall 

`= 600  members `
