The answer to your question is: 8 boxes
Step-by-step explanation:
First, calculate the area of the bases (6 x 6)
Area of a rectangle = 6 x 6 = 36, there 2 bases
then = 36 x 2 = 72 ft2
Area of a rectangle (lateral faces) = 6 x 3 = 18
there are 4 faces = 18 x 4 = 72
Total area = 72 + 72 = 144 ft2
Finally # of boxes = 1152/144 = 8
