Unfortunately, you're going to have to redo your calculation for your
project. The first sentence, the one beginning "The copper tubing
expands by...", states the formula. The second sentence gives a
specific example. In the example, the temperature has been increased
100 times (1.8 x 100 = 180), therefore the length must also be increased
100 times (1.7 x 10 to the minus 5 x 100 = 1.7 x 10 to the minus 3). I
hope that makes it a little more clear.
