    The correct choices are numbers four and five. To find the volume of this pier amid, you will use the formula.

    V = 1/3 x B x h, where B represents the area of the base.

    1/3 x 108 x 15

    V = 540 in.³.

    To find the volume of a rectangular prism with these dimensions you would also use a formula.

    V = Bh

    108 x 15

    V = 1620 in.³ This is triple the volume of the pyramid.
