Answer»

Dimensions of roomLength = 25 m, Breadth = 9.6 m, Height =?

Number of person in room = 75and each person require 16 m^3 air

Then volume of room = 75*16 = 1200 m^3

We know, Volume of room = Length*Breadth*Height

Therefore, Length*Breadth*Height = 120025*9.5*Height = 1200Height = 1200/(25*9.5) = 48/9.5 = 5.05 m

Height of room = 5.05 m
