A dining hall has dimensions `50mxx10mxx3.5m`. Calculate the mass of air in the hall. Given, density of air`=1.30(kg)/(m^3)`.

Text Solution

Verified by Experts

volume of the hall, `V=50mxx15mxx3.5xx=2626m^3`
density of air, `d=1.30(kg)/(m^3)`
Mass of air in the hall, `M=Vxxd=(2625m^3)xx(1.30(kg)/(m^3))=3412.5kg`.
