Question
A hall is of length 16m , breadth 14m & height 5m . Calculate the no of persons that can be accommodated in the hall , assuming 3.5m3 of air is required for each person?
Answer: Option C
- ∴Volume of the hall = length × breadth × height
= 16 × 14 × 5
= 1120 m3
Volume occupied my 1 man = 3.5 m3
3.5 m3 of air occupied my 1 man
1120 m3 of air occupied my ( 1/3.5)x 1120= 320 man
Therefore, number of men that can be accommodated = 320men
