Question

I need to calculate the mass. Can I get some help pls? You can use any values you think is the best :) Thanks!

Answer 1

Here is a reference that give the Density of Air :

`1.225" kg/m"^3`

The volume of the room is:

`V = (10" m")(20" m")(4" m")`

`V = 800" m"^3`

Multiply the density by the volume of the room:

`(1.225" kg/m"^3)(800" m"^3) = 980" kg" color(red)(larr" this is the mass"`
