Answer:
112= 2ft x 2ft x3 1/2ft
Explanation:
The reason 112 is the correct answer is since each box is half a foot on each side, we are able to fit 4 on the width and 4 also tall while being to put 7 long, since 4 half feet fit in 2 feet. This would make 2ft = 4 boxes,
3 1/2ft= 7 boxes meaning that we have the equation 4x4x7 which equals 112
