A: The average length of an unsharpened pencil is 7.5 inches, and smaller library or golfing pencils are usually 3 1/2 inches in length. Hexagonal-shaped pencils are a quarter of an inch thick at the smallest point.
Pencils can be made from different woods, in the U.S. they are mainly made from California Incense Cedar (as a result of a shortage of Red Cedar). Imports might use other trees including rainforest hardwoods. The number of trees needed depends on how big the trees are, so this can vary a lot depending on the tree. The California Incense Cedar has varying dimensions but on average is about 60 feet high and 3-4 ft in diameter. We will use 60 feet and 3.5 feet in diameter to calculate the available volume of wood. (This tree can also live to be 500 years old). Using these dimensions, and 15 billion pencils per year, results in a need for about 60,000 trees.
