Scale :1 box=3 inches. Convert this scale drawing of a bureau drawer so that it has a scale of 1 box=6 inches. The length in the scale drawing shown is 8 boxes. What will be tbe length in boxes of the new scale drawing?

If 1 box represents 3 inches and the length in the scale drawing is 8 boxes, then the length in the scale drawing is 8 x 3 = <<8*3=24>>24 inches.

To convert this scale drawing to a scale of 1 box = 6 inches, we need to multiply the length by a factor of 2 (6/3).
So the length in the new scale drawing will be 24 x 2 = <<24*2=48>>48 inches.
Since 1 box represents 6 inches, the length in boxes of the new scale drawing will be 48/6 = <<48/6=8>>8 boxes. Answer: \boxed{8}.
