To convert the scale drawing to a scale of 1hnx = 6 inches, we need to determine the length in boxes of the new scale drawing.
From the given information, we know that 1 inch in the original scale corresponds to 1 box (e / 1 * box = 3in). This means that each box in the original scale represents 1 inch.
To find the length in boxes of the new scale drawing, we multiply the length in inches by the scale factor (6 inches / 1 inch):
Length in boxes = Length in inches * Scale factor
Length in boxes = 8 boxes * 6 inches / 1 inch
Length in boxes = 48 boxes
Therefore, the length in boxes of the new scale drawing will be 48.
