Question

75 persons can sleep in a room 25 m by 9.6 m .if each person requires 16 m3 of air; find the height of the room

Answer 1

Length of room=25m
Breadth of room=9.6m
Air required by people =16m3
Now,
lbh=volume of room
25×9.6×h=16
240×h=16
h=16×75÷240=5
because each person requires 16m3 of air
Therefore, height of room is 5 m.

Answer 2

Dear Student,

◆ Answer -

Height of the room = 5 m

● Explaination -

Total air volume required for 75 persons =

Volume = 75 × 16

Volume = 1200 cu.m

Let x be height of the room. Volume of room is calculated by formula -

Volume = 25 × 9.6 × x

1200 = 25 × 9.6 × x

x = 1200 / (25 × 9.6)

x = 5 m

Hence, height of the room is 5 m.

Thanks dear. Hope this helps you...
