16Board feet are used to measure the total length (in feet) of boards that are 1 inch thick and 1 foot wide that can be cut from a tree to make lumber. You can use the equation l=0.011a²-0.68a+13.31 to estimate the number of hundred of board-feet available in a certain type of tree, where "l" is the number of board-feet and "a" is the age,in years,of the tree. What is the approx. number of board-feet available to cut from a 40 year old tree? A student said the answer was 371. Is this answer true or false?
