Question

4. 75 persons can sleep in a room 25 m by 9.6 m. If each person requires 16 m² of air, find the height of the room.
​

Answer 1

Step-by-step explanation:

Total number of persons that can sleep in a room =75

Volume of air per person =16m ²

Total required air =16×75=1200m²

Volume of rectangle room =25×9.6×h=240h m²

⇒240h=1200

⇒h=5 m

Answer 2

Answer:

5m

Step-by-step explanation:

Let the height be h metre.

Now the equation becomes:

75X16=25X9.6Xh

=> h=75X16/25X9.6

=5m
