    Given:

    Area of cross section = 78.5 ft²

    Ratio of AB to BC = 5 : 4

    AB=10 ft

    To find BC, we get

    5/4=10/BC

    5BC=40

    BC=8 ft

    Now formula for volume of prism:

    V=Area of base x height

    Put values

    V=78.5 x (10+8)

    V=78.5 x 18

    V=1413 ft²

    Answer: 1413 ft²
