Question

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

Answer 1

We know that volume of cuboid = length × breadth × height

V = 16 × 12.5 × 4.5 = 900 m³

Also given that 3.6 m³ of air is required for each person

Therefore, total number of persons can be accommodated in a hall is

Total volume/ volume required by each person

= 900/3.6

= 250 people.
