How many persons can be accommodated in a hall of length 16 m. breadth 12.5 m and height 4.5 m, assuming that 3.6 m3 of air is required for each person?
Length of hall (l)=16 m
Breadth (b)=12.5 m
height (h)=4.5 m
∴ Volume of air in it =l×b×h
=900m3 Air for one person is required =3.6m3
∴ Number of person which can be accommodated in the hall =900÷3.6
