Some of the supplies are packed inside a cube-shaped box with side lengths of 4 1/2 in. . These boxes are then packed into a shipping box with dimensions of 18 in. * 9 in. * 4 1/2 in. . How many boxes of office supplies can be packed into the larger box for shipping? Show your work.

Answer 1

Ok, so the bigger box has sides that are multiples of 4.5 inches:
18in * 9in * 4.5in. 
in terms of the cubes that go inside them, the bigger box is:
4 box * 2 box * 1 box, so you know that 8 boxes fit inside.
