The volume of seeds in the package must be equal to the volume of the feeder in order to fill it completely. The volume of the conic feeder is given by: V(f) = (πr²h)/3 And volume of the cylindrical package is given by: V(p) = πr²h Equating the two and substituting values: (π x 3² x 24)/3 = π x 6² x h h = 2 inches
