Answer:
[tex]380\text{ ft}^3[/tex]
Step-by-step explanation:
We have been that a classroom is 19 ft long 2 ft wide and 10 feet high. We are asked to find the number of cubic feet of air in the room.
To find the number of cubic feet of air in the room, we will find the volume of the given room by multiplying all of its side as:
[tex]\text{Volume of the room}=\text{19 ft}\times \text{2 ft}\times\text{10 ft}[/tex]
[tex]\text{Volume of the room}=380\text{ ft}^3[/tex]
Therefore, there are 380 cubic feet of air in the room.
