Part 2: How much wire will you need?

Next, you will have to figure out how much wire you will need. On the next page there is a drawing of the room that needs rewiring. It has all the measurements that you will need to use.

Now look at the chart below. For each step in the chart, you will have to add more than one measurement. Look at the diagram to see all the lengths that you will need for each step.

Fill out the chart below using the measurements from the diagram.
