Consider the area of the room. How many labs would it take to cover the entire surface of the earth? *remember it's easier to convert km to m.

The average circumference of the easth is 40042km. The area of a sphere is 4pir^2, the circumference is pid and the volume is 4/3pir^3.
Info:
28,000,000 ping pong balls to fill a whole room
Surface area of the whole room= 287.55m
The Volume of the whole room is 1841.825m3
It would take 2.15*10^16 rooms for 1mol ball.
