A cubical float, 1.22 m on a side, weighs 1.78 kN and is anchored by means of a concrete block that weighs 6.67 kN in air. If 229 mm of the float is submerged when the chain connected to the concrete is taut, what rise in water level will lift the concrete off the bottom? Concrete weighs 23.56 kN/m3
