It takes about 100 lights to cover three feet of height on an "average" Christmas tree. The tree for the state capitol is 24 feet high and about five times as big around as the average tree at the base, tapering to about double the typical tree's circumference in the top 6 feet. About how many lights will it take to decorate this tree?
