(1point)

In the original scale drawing, 10 boxes represent a length of 10 boxes x 6 inches/box = <<10*6=60>>60 inches.

To convert to a scale factor of 1 box = 12 inches, we need to double the length of each box.
Therefore, in the new drawing, the length of each box will be 60 inches / 2 = <<60/2=30>>30 inches. Answer: \boxed{30}.
