5 Boxes

Step-by-step explanation:

Volume is Length * width * height

1 box = 4.5* 2 *4= 36

Each box is 36 cubic feet. Now divide the closet size by box size

185 cubic feet/36 cubic feet per box = 5.138

Since you can't have .138 of a box, and rounding up to 6 boxes is too much, the closet will hold 5 boxes (with .138 cubic feet left over).
