Question

What is the scale factor of a drawing if the scale is 1 inch = 6 feet?
but if it 1:72 what is that answer

Answer 1

The scale factor of the drawing is 1: 72 in inches.

Step-by-step explanation:

Step 1:

If 1 inch on the drawing is equal to 6 feet of the unscaled drawing, we can determine the scale factor by dividing the measurement after scaling by the same measurement before scaling.

Here the measurement after scaling is 1 inch and the same measurement before scaling is 6 feet.

Step 2:

The units are different so we must convert them into the same units first.

If 1 feet = 12 inches, then 6 feet = 72 inches.

So the scale factor is 1: 72.
