    Re: square ft to cubic yards

    I don't think you understand that a square foot is a 2 dimentional unit of measure and a cubic foot is a 3 dementional unit of measure. ft square (2) to yard cube (3) cannot be done without all 3 directions measured. You can easily change 6ft X 3ft x 3" to a cubic yard though because you have the third dimention (height or thickness). Its like trying to convert a gallon to an inch. One is a unit of volume the other is a linear measurement. There is too much information missing to make that type of convertion.

        Volume to be filled
        125 ft x 35 ft x 0.25 ft = 1094 ft³
        1 yd³ = 27 ft³, so 40.5 yd³

        The dirt is measured and delivered loose and will compact over time. Order about 20% more, say 49 yd³

            The volume is 23 ft x 23 ft x (2/12) ft = 88.2 ft³ or 3.3 yd³

            You don't say what you are covering with, but a lot of materials are delivered loose and will compact over time. You may wish to add 20% or so to allow for that.

                240 ft² x 4 in x 1 ft/12 in x 1 yd³/27 ft³ = 2.96 yd³

                      You need the thickness.

                      240 square feet * ( XX inches / 12) feet = cubic feet
                      cubic feet / 27 cubic feet/cubic yard = cubic yards
