A solid consists of a right circular cylinder of radius \(r\) cm and height \(h\) cm, surmounted by a right circular cone having the same base radius \(r\) and height \(\frac{h}{2}\) cm. The height of the cylinder is twice its radius (\(h = 2r\)). If the total exterior surface area of the solid (including the base of the cylinder) is \(500\ \text{cm}^2\), find the volume of the solid, correct to the nearest cubic centimetre.
