How many persons can be accommodated in a big-hall of dimensions 40 m, 25 m and 15 m ; assuming that each person requires 5 m3 of air?
Answers:
[No. of persons = vol. of the hall/vol. of air required for each person]
Length of the hall = 40 m
Breadth of the hall = 25 m
Height of the hall = 15 m
Volume of the hall = L × B × H
= 40 × 25 × 15
= 15000 m3
Volume of the air required for each person = 5 m3
No. of persons who can be accommodated
= volume of the hall/Volume of air required for each person
= 15000 m3/5m3
= 3000
