The area of the floor of a room is `15\ m^2dot` If its height is 4 m, then the volume of the air contained in the room is (a) `60\ d m^3` (b) `600\ d m^3` `6000\ d m^3` (d) `60000\ d m^3`

Explanation

Area of the floor = `15 m^2`

`lxxb=1500 dm^2`

Here, height (h)=`4m`=`40dm`

Now, Volume of the air contained in the room=`lxxbxxh`

`1500xx40`= `60000 dm^3`

Hence, option(d) is correct.
