Scale factor: 1 box = 6 inches

To convert the length from a scale factor of 1 box = 6 inches to a scale factor of 1 box = 12 inches, first calculate the actual length in inches based on the original scale.

The length in the scale drawing is 10 boxes.

Using the original scale: 10 boxes × 6 inches/box = 60 inches

Now, to convert this length to the new scale (1 box = 12 inches), we can find out how many boxes this length would be:

60 inches ÷ 12 inches/box = 5 boxes

So, in the new drawing, the length will be represented by 5 boxes.

The answer is 5.
