The principle is that the total volume of the metal remains constant when it is melted and reshaped. The volume of the four spheres is equated to the volume of the wire (cylinder).
After melting four metallic spheres of diameter 15 cm in a factory, wire of diameter of the cross-section of 0.2 cm was drawn. What would be the length of wire so obtained?
