Question

2. The dimensions of a hall are 10 mx 7 m x 5 m.
If the density of air is 1-11 kg m find the mass
of air in the hall
​

Answer 1

Explanation:

Denisity=mass. /volume

Mass= volume ×Denisity

Volume of the room =lbh (where l=10,b=7,h=5)

=10×7×5

=350m^3

Now,

Mass =volume ×Denisity

(Denisity given by u is not so clear so i am taking 1111, 111, 11 and 1.11 kg/m3 as Denisity with respect to the Denisity given bu u.)

If the Denisity is11111 then

Mass=350×1111=388850kg

If the Denisity is 111 then

Mass =111×350=38850kg

If the Denisity 11 then

Mass = 350×11=3850kg

If the Denisity is 1.11

Mass =350×1.11=388.5

Hope i solved the problem given by u

(After this please type the question clearly)
