In stimulate to discover the answer come this question, you need to recognize the adhering to equation:

m = dv

Where m is mass, d is density, and v is volume. In this case, friend are in search of mass, you have volume. Therefore you need to know the density of air.

As is turns out, the approximate density of air in ~ sea level (and in ~ 20 C) is 1.2 kilograms every cubic meter.

First, us must uncover the the volume of the room, i beg your pardon you gain by multiply its dimensions. That tells us that the room is 500 m^3. Now we deserve to plug in the numbers

m = 500*1.2

Which provides us

m = 600 kilograms.

So, the wait in her room weighs roughly (depending on how wet the is, what temperature, etc) 600 kg.
