10m^3 of air weigh 13 kgHow much does the air weigh in a room 4.2m long, 3.5m wide, and 2.6m high?
Accepted Solution
A:
The weight of air in the room is 49.69kgStep-by-step explanation:First of all we have to calculate the volume of the air present in the room.HereLength = 4.2mWidth = 3.5mHeight = 2.6mThe volume of the air in the room is:[tex]V = Length*Width*Height\\= 4.2*3.5*2.6\\=38.22\ m^3[/tex]Now we have to find the density of the airDensity is the mass of a matter in per unit of volumeDensity = 13/10 = 1.3 kg/m^3So the weight of air is: [tex]Volume * Density\\= 38.22*1.3\\=49.686\\=49.69\ kg[/tex]The weight of air in the room is 49.69kgKeywords: Volume, DensityLearn more about volume at:brainly.com/question/11566221brainly.com/question/12884373#LearnwithBrainly
