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 m³ of air?

Answer 1

Given,

Dimension of cinema hall = 100m × 50m × 18m

Volume of cinema hall = 100 × 50 × 18 m³

Number of persons can sit in cinema hall = \(\cfrac{volume\,of\,hall}{one\,person\,air\,volume}\)

\(=\cfrac{100\times50\times18}{150}\) = 600
