    l = 626.4/bh

    Step-by-step explanation:

    A triangular prism have a base that is triangular in shape. The volume of a prism has the volume represented as follows.

    volume = Al

    where

    A = Base area

    l = width

    Since the base is a triangle the base area will be the area of a triangle. Therefore,

    volume of a triangular prism = 1/2bh l

    where

    b = base of triangle

    h = height of triangle

    volume = 313.2 ft³

    313.2 = 1/2bh l

    Make the width (l) subject of the formula

    multiply both sides by 2

    626.4 = bhl

    divide both sides by bh

    l = 626.4/bh

    l = 626.4/bh

    recall l = width
