The length of the boxes in the new drawing can be calculated by multiplying the length in the scale drawing shown (10 boxes) by the ratio of the new scale factor to the old scale factor.
Since the new scale factor is 1 box = 12 inches and the old scale factor is 1 box = 6 inches, the ratio of the new scale factor to the old scale factor is 12/6 = 2.
Therefore, the length of the boxes in the new drawing is 10 boxes * 2 = 20 units.
So, the correct answer is 20.
