Quizplus · Accepted Answer

First, convert the height of the ceiling to inches: 
14 feet = 14 x 12 inches/foot = 168 inches
Next, divide the height of the ceiling by the height of one box:
168 inches ÷ 11 inches = 15.3 
Round down to the nearest whole number to account for any space needed between boxes:
15 boxes can be stacked in one pile. 
Therefore, the best choice is C) 12, as stacking 13 boxes may be too high and potentially dangerous.
