Answer 1

To find the width in boxes of the new drawing after changing the scale, we can follow these steps:

1. **Determine the current dimensions in inches:**
- The current width in the scale drawing is 3 boxes. With the scale of 1 box = 4 inches, the actual width in inches is:
\[
3 \text{ boxes} \times 4 \text{ inches/box} = 12 \text{ inches}
\]

2. **Convert to the new scale:**
- We need to express the width in terms of the new scale, which is 1 box = 2 inches.
- To find the new width in boxes, we take the actual width in inches and divide it by the number of inches per box in the new scale:
\[
\text{New width in boxes} = \frac{12 \text{ inches}}{2 \text{ inches/box}} = 6 \text{ boxes}
\]

Therefore, the width in boxes of the new drawing will be **6**.
