Answer 2

Answer:

180 people

Step-by-step explanation:

$\text{Given Length (l), Breadth (b), and height of room are 20 m, 10 m, and 4.5 m respectively.}\\\\\therefore \: \text{Volume of room in cubic meters = 20*10*4.5 = 900 m}^3\\\\\text{Volume per person = 5 m}^3\\\\\therefore \: \text{No. of people that can be accommodated = 900 \div 5 = 180 people.}$
