    Answer:

    Are they going to build the fence on the edge of the pool?  How are they going to get into the pool?  This question is illogical, however….

    Step-by-step explanation:

    A square pool is also wierd.

    Volume Pool = side × side × depth

    Volume Pool / depth = side²                 solve for side

    side² = Volume Pool / depth

    the fence is 3.5 feet tall

    Fencing sqft one side = side × fence height  for ONE side

    Total Fencing = 4 × Fencing sqft one side

    side² = 3464 ft³ / 8 ft

             = 422 ft²

    side  =  √422 ft²

            =  20.54 ft

    Fencing area one side  = 20.54 × 3.5

           = 71.899 ft²

    Total fencing = 4× 71.899 ft²

          = 287.6 ft²      to the nearest tenth     <——————–   FINAL ANSWER
