Question 1082523: A piece of copper wire is 1/8" in thickness and is 20 yards in length. Determine weight of wire. Copper wire weighs .321 lbs. per cu. in.
3.1416 * 0.0625 * 0.0625 * 720(yds. to in.) = 8.83575 cu. in. (volume of wire)
8.83575 * .321 = 2.8362 lbs. = 45.3792 oz.
What parts are correct? Non-homework. Thanks.
