Answer:
The Answer is that 9 small boxes will completely fill the bottom of the large box.
Explanation:
The bottom box is a square with each side 18.3 inches. The smaller boxes are square with each side 6.1 inches. Divide the large box side measurement by the small box measurement:
18.3 / 6.1 = 3 small boxes
Three small boxes will fit across each side. That is 3 boxes wide and 3 boxes long. The number of boxes will be:
3 * 3 = 9 small boxes will completely fill the bottom of the large box.
