Maria needs to convert this scale drawing from a scale of 1 box = 4 inches to a scale of 1 box = 2 inches. The width in the scale drawing shown is 3 boxes. What will be the width in boxes of the new drawing?

If 1 box = 4 inches in the original drawing, then the width of the original drawing in inches is 3 boxes * 4 inches/box = <<3*4=12>>12 inches.

If 1 box = 2 inches in the new drawing, then the width of the new drawing in boxes is 12 inches / 2 inches/box = <<12/2=6>>6 boxes. Answer: \boxed{6}.

To convert the scale drawing from a scale of 1 box = 4 inches to a scale of 1 box = 2 inches, we will be scaling down.

The original width in the scale drawing is 3 boxes.

First, we need to find the length of 1 box in the original drawing. Since the scale is 1 box = 4 inches, the length of 1 box in the original drawing is:

1 box * 4 inches/box = 4 inches.

Now, we need to find the length of 1 box in the new drawing. Since the scale is 1 box = 2 inches, the length of 1 box in the new drawing is:

1 box * 2 inches/box = 2 inches.

To find the width in boxes of the new drawing, we divide the original length in inches by the length of 1 box in the new drawing:

4 inches / 2 inches/box = 2 boxes.

Therefore, the width in boxes of the new drawing will be 2 boxes.

To solve this problem, we need to determine the width of the new drawing in boxes. First, let's find out the width of the current drawing in inches.

Given that the scale of the current drawing is 1 box = 4 inches, and the width in the current drawing is 3 boxes, we can calculate the width of the current drawing in inches by multiplying 3 boxes by 4 inches per box:

Width in inches = 3 boxes * 4 inches/box = 12 inches.

Now, we can use the new scale of 1 box = 2 inches to find the width in boxes of the new drawing. We need to find out how many boxes can fit into the width of 12 inches using the new scale.

Since the scale is 1 box = 2 inches, we can divide the width in inches by the amount of inches per box:

Width in boxes = 12 inches / 2 inches/box = 6 boxes.

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