Problem Statement

A triangular pyramid O.ABC O.ABC with base ABC ABC has the property that the lengths of the altitudes from A A, B B and C C are not less than \frac{OB \plus{}OC}{2}, \frac{OC \plus{} OA}{2} and \frac{OA \plus{} OB}{2}, respectively. Given that the area of ABC ABC is S S, calculate the volume of the pyramid.
