To convert the scale from 1 box = 4 inches to 1 box = 2 inches, we first need to determine how many inches the original width corresponds to.
Given that the original width in the scale drawing is 3 boxes:
- With the scale of 1 box = 4 inches, the width in inches is: \[ 3 \text{ boxes} \times 4 \text{ inches/box} = 12 \text{ inches} \]
Now, we need to convert this width back to boxes using the new scale of 1 box = 2 inches:
- We calculate the width in boxes for the new scale: \[ \text{Width in boxes} = \frac{12 \text{ inches}}{2 \text{ inches/box}} = 6 \text{ boxes} \]
Thus, the width in boxes of the new drawing will be 6.
Correct answer: A. 6
