A concrete cube 260 mm on each is to be held in equilibrium under water by attaching a Lightweight foam buoy to it, as shown. (In theory, the attached foam buoy and concrete cube, when placed under water, will neither rise nor sink.) If the specific weight of the concrete and foam are 23.875 kNm3 and 0.55 N/m3, respectively, what is the minimum required volume of the foam. Neglect the weight of the wire.
