  1. 18Ft^2*h1 = 72Ft^3
    h1 = 72Ft^3/18Ft^2 = 4 Ft.

    A = (8Ft/4Ft) * 18Ft^2 = 36 Ft^2 = Area
    of the base.

    V = A*h = 36Ft^2 * 8Ft = 288 Ft^3.

  2. Correction:
    A =(8/4)^2 * 18 = 72 Ft^2 = Area of the
    base.
    V = A*h = 72 * 8 = 576 Ft^3.

    OR
    V = (8/4)^3 * 72Ft^3 = 576 Ft^3.
