How many persons can be accommodated in a hall of length 16 m.

Question:

How many persons can be accommodated in a hall of length 16 m. breadth 12.5 m and height 4.5 m, assuming that 3.6 m3 of air is required for each person?

Solution:

Total volume of the hall $=(16 \times 12.5 \times 4.5)=900 m^{3}$

It is given that $3.6 \mathrm{~m}^{3}$ of air is required for each person.

The total number of persons that can be accommodated in that hall $=\frac{\text { Total volume }}{\mathrm{Volume} \text { required by each person }}=\frac{900}{3.6}$

$=250$ people
