one IMG_1085 The plastic block shown below measures I.5 m x/.s m x(.7 m and has a specific gravity of 0.38. The concrete block B (density = 2400 kg/m*) is suspended from the corner of the plastic block by means of a cable and the plastic block is thus floating in the lake (T = 15°C) in the orientation shown. Determine the volume of the concrete block (units of liters) noting that it does not rest on the bottom of the lake. Neglect the weight and volume of the cable in your analysis. %3D 1.7 m 0.5 m Water Cable
