Sometimes you find mathematics being used in the oddest places. And, the special use of a formula seems to give a sense of truth.
Consider this tidbit: "To determine the number of lights needed for your Christmas tree, multiply height of tree by width of tree base by three. For miniature lights, multiply height of tree by width of tree by eight."
Do you believe this? Walk by a decorated tree this holiday season, check it out...and let the owner know if it has too few or too many lights on their tree!
Also, the Capitol tree (2009) measured 65 feet high and had a width of 30 feet...thus, how many lights were needed?
