To determine the width in boxes of the new drawing with a scale of 1 box = 2 inches, we first need to calculate the actual width in inches from the original drawing.
Since the original scale is 1 box = 4 inches and the width is 3 boxes: Width in inches = 3 boxes * 4 inches/box = 12 inches.
Now, we want to convert this width to the new drawing scale of 1 box = 2 inches: Width in boxes for the new scale = Width in inches / 2 inches/box = 12 inches / 2 inches/box = 6 boxes.
Therefore, the width in boxes of the new drawing will be 6.
