1. How much land should be set aside for a new city landfill?

    SINCE:  volume = area x depth (from the definition above)
    THEREFORE:  area = volume
                                          depth
    BUT:  density = weight (from the definition above)
                               volume
    THEREFORE:  VOLUME = WEIGHT
                                                    DENSITY
    SUBSTITUTION IN THE AREA EQUATION ABOVE:
                                    area =          weight
                                                density x depth
    GIVEN:  depth = 50 feet
                   density = 1,500lb/yd(3) or 55.5lb/ft.(3)
    SOLVE FOR THE AREA IN SQUARE FEET, THEN CONVERT TO ACRES.
