dimensions 50m * 15m * 3.5m.
volume= l*b*h
= 50m * 15m * 3.5m.
= 2625m3
density of air =1.30kg/m3
..mass= denstiy * volume
= 1.30kg/m3* 2625m3
= 3412.5kg is the answer
volume= l*b*h
= 50m * 15m * 3.5m.
= 2625m3
density of air =1.30kg/m3
..mass= denstiy * volume
= 1.30kg/m3* 2625m3
= 3412.5kg is the answer

Volume of the dining hall = Volume of air in it
Volume = 50 x 15 x 3.5 = 2625 m^3
Mass = density x volume
Mass = 1.30 x 2625 = 3412.5 kg =
Volume = 50 x 15 x 3.5 = 2625 m^3
Mass = density x volume
Mass = 1.30 x 2625 = 3412.5 kg =
