    irrational root of polynomial

    The width of the shipping crate shown is to be 2 feet greater than its height and the length is to be 7 feet greater than its width, and its volume is to be 195 cubic feet. Use the bisection method or a graphing calculator to find the height of the crate to the nearest tenth of a foot.

    W = H + 2

    L = W + 7 = (H + 2) + 7 = H + 9

    V = LWH = (H + 9)(H + 2)(H) = 195

    get out your calculator and find H.
