The Ferrari dealership in Springfield filled a glass case with ball bearings. The person who can most closely guess the number of ball bearings in the case wins a brand new 360 Modena. You notice that the bottom layer has 150 ball bearings, and there are 23 layers. Your best guess is there are _________ ball bearings.

If the bottom layer has 150 ball bearings, it is safe to assume that all layers have around 150 ball bearings. And you also know the number of layers!

anyalong78, what shape does the glass case have? This problem is too vague.
