Question 1042777
The diameter of each ball is r*2 = 2r. So each ball is 2r high and 2r wide
3 balls stacked one on top of the other:
3(2r) = 6r is the height of 3 balls
If your box is 3r wide, since the balls are 2r wide you can only get one sleeve in 3r
If your box is 6r long, you can get 3 sleeves (6r/2r= 3)
If your box is 12r tall, you can get 12r/2r = 6 balls. Since each sleeve has 3 ball stacked up one on top of the other, you can get 2 sleeves one on top of the other in your box.
3*2 = 6 sleeves in each box (3 deep, 2 high, 1 wide)
