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?
We know that,
Volume of cuboid = Length × Breadth × Height
Therefore,
Total volume of hall = 16 × 12.5 × 4.5
= 900 m3
It is given in the question that 3.6 m3 of air is required for each person
Therefore,
Total number of persons that can be accommodated in the hall = 
= 
= 250 people
