    You could use that formula to help you:

    Amount = Concentration x Volume

    So, find the amount of sand added from the 2 m^3 35% soil,
    find the amount of sand added from the 6 m^3 15% soil,
    add both amounts,
    find the total volume that you get,
    divide the total amount of sand by the total volume.

    Can you post what you get? :)
