Answer: The mass of air present in the room is 37.068 kg
Explanation : Given,
Length of the room = 10.0 ft
Breadth of the room = 11.0 ft
Height of the room = 10.0 ft
To calculate the volume of the room by using the formula of volume of cuboid, we use the equation:
where,
V = volume of the room
l = length of the room
b = breadth of the room
h = height of of the room
Putting values in above equation, we get:
Conversion used :
Now we have to calculate the mass of air in the room.
Conversion used : (1 kg = 1000 g)
Therefore, the mass of air present in the room is 37.068 kg
