The dimensions of a hall are 40 m, 25 m and 20 m. If each person requires 200 cubic meters, find the number of persons who can be accommodated in the hall.
Answer & explanation
Correct answer: option 4
Volume of the hall ( l x b x h )→ 40 x 25 x 20 = 20000
Area required by a person → 200 cubic meters
Number of persons → \(\frac{ 20000}{ 200}\) = 100
Thus, 100 persons can be accommodated in that hall.
