Tennis balls are packed into a square box 12 in. on one side. the tennis balls can be touching, but they can't be compressed. the remaining space is filled with packing beads.

how many tennis balls can be packed onto the box? (note: the diamenter of a tennis balls is 2.5 in.)

what is the volume occupied by the packing beads?

A tennis ball is 2 in so you would divide 12 by 2 and 6 balls would fit on one side so 6*6 is 36 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
