Extracted text: 74.A cube 2.2 feet on an edge has its lower half of s.g. =1.6 and upper half of s.g. = 0.7. It rests in a two-layer fluid, with lower s.g. = 1.4 and upp er s.g. = 0.8. Determine the height h of the top of the cube above the interface. See Figure 33. S.g. = 0.8 S.g. = 0.7 h 2.2 ft s.g. = 1.6 2.2 h S.g. = 1.4 2.2 ft
