In many locations, such as Lake Washington in Seattle, floating bridges are preferable to conventional bridges. Such a bridge can be constructed out of concrete pontoons, which are essentially concrete boxes filled with air, Styrofoam, or another extremely low-density material. Suppose a floating bridge pontoon is constructed out of concrete and Styrofoam, which have densities of 2200 kg/m³ and 50.0 kg/m³. What must the volume ratio of concrete to Styrofoam be if the pontoon is to float with 45.9% of its overall volume above water?
