An auditorium measures 40.0 m 3 20.0 m 3 12.0 m. the density of air is 1.20 kg/m3. what are (a) the volume of the room in cubic feet and (b) the weight of air in the room in pounds?

We use the formula,

m = V\rho

Here, m is the mass, V is the volume and   density

Also

Here l is length, w is width and h is height.

(a) The volume of the room,

The volume of the room in cubic feet,

(b) Now the mass of the air in room,

.

Therefore, the weight of the air in room,

.

The weight of air in the room in pounds,

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
