To find the new length in boxes of the scale drawing when changing the scale from 1 box = 3 inches to 1 box = 6 inches, we can follow these steps:

  1. Calculate the actual dimensions in inches using the original scale:

    • The original length of the rectangle in the scale drawing is 8 boxes.
    • Since each box represents 3 inches, the actual length is: \[ \text{Actual Length} = 8 \text{ boxes} \times 3 \text{ inches/box} = 24 \text{ inches} \]
  2. Determine the new length in boxes using the new scale:

    • Now, with the new scale of 1 box = 6 inches, we need to find out how many boxes correspond to the same actual length of 24 inches.
    • We can set up the equation: \[ \text{New Length in boxes} \times 6 \text{ inches/box} = 24 \text{ inches} \]
    • Solving for the new length in boxes: \[ \text{New Length in boxes} = \frac{24 \text{ inches}}{6 \text{ inches/box}} = 4 \text{ boxes} \]

Therefore, under the new scale of 1 box = 6 inches, the length in boxes of the new scale drawing will be 4 boxes.
