    Step-by-step explanation:

    We would apply the formula for determining the volume of a square based pyramid which is expressed as

    Volume = 1/3 * base area * height

    From the information given,

    Side length = 230m

    Height = 145m

    Since the base is a square,

    Base area = 230² = 52900

    Therefore,

    Volume = 1/3 * 52900 * 145

    Volume = 2556833.3 cubic meters

    The amount of stone needed is expressed in volume.
