1. how many tennis balls would fill your classroom?
(note- classroom= 15m by 20m)
2. how many bananas would fill a garbage bag?
can someone plz do atleast one of them? but the first one is more important!

The radius of a tennis ball, is about 3.25cm
Assuming all the tennis balls fill the classroom with no space left over, to find how many will fit, simply divide the volume of the classroom by the volume of the tennis ball
