标题: How many balls?

1.      We have a large number of iron balls, all exactly two cm in diameter, which we need to move. We need to pack them into a large wooden rectangular crate that is 24.9 cm long, 28.8 cm wide, and 14 cm deep. What is the greatest number of the balls that can be packed into the crate?
