Scale factor: 1 box = 6 inches

Maisie needs to convert this scale drawing from a scale factor of 1 box = 6 inches to a scale factor of 1 box = 12 inches. The length in the scale drawing shown is 10 boxes. What will be the length of the boxes in the new drawing?

To convert the scale factor from 1 box = 6 inches to 1 box = 12 inches, we need to double the length of each box.

Since the length in the scale drawing is 10 boxes, the length in the new drawing will be 10 * 2 = <<10*2=20>>20 boxes.
