To convert the width from the original scale to the new scale, first, determine the actual width in inches based on the original scale.
-
The original scale is 1 box = 4 inches.
Given that the width in the scale drawing is 3 boxes:
\( 3 \text{ boxes} \times 4 \text{ inches/box} = 12 \text{ inches} \) -
Now, convert this width to the new scale of 1 box = 2 inches.
To find how many boxes correspond to 12 inches at the new scale:
\( \frac{12 \text{ inches}}{2 \text{ inches/box}} = 6 \text{ boxes} \)
Therefore, the width in the new drawing will be 6 boxes.
