    Using the given information find the length and width of the base:

    Perimeter = 2L + 2W

    L = 3W

    Replace L in the first equation:

    Perimeter = 2 (3W) + 2w

    96 = 2 (3W) + 2W

    Simplify:

    96 = 6W + 2W

    96 = 8w

    Divide both sides by 8:

    w = 96 / 8

    w = 12

    The width is 12 inches.

    The length = 3 x 12 = 36 inches.

    Volume = L x W X H

    Volume = 36 x 12 x 14

    Volume = 6,048 cubic inches.
