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.

100

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.
