    36in²

    Step-by-step explanation:

    This problem bothers on the mensuration of solid shapes, a square based pyramid.

    Step one

    The formula for the volume of a square based pyramid is

    V=a²h/3

    Where a = side of base

    h = height

    Given data

    Volume = 108in³

    Height h = 8 in

    We can solve for the base a by substituting our data

    108 = a² * 8/3

    a² = (108*3) / 8

    a² = 40.5

    a = √40.5

    a = 6.36in

    To the nearest whole number

    a = 6in

    The area of the square based = 6*6

    = 36in²
