The container pictured below on the left is filled with water at 20°C, just to the overflow spout. A cube of wood with edges of 1.0 in. is floated on the water, and 10.8 mL of water is collected, as shown on the right. Calculate the density of the wood, and express your result with the maximum number of significant figures permitted in this experiment.

1 inch on edges is 2.54 cm on edge or 16.48 cm3
10.8 ml of water weighs 10.8 g and that is what is displaced so what the block weighs.
density is weight divided by volume compared to the 1.0 of water thus 0.655 to three significant figures which both the edge size and volume are given that way.

The wood cube will lay suspended until an outside force acts with it causing a reaction. The most likely force would be gravity from other floating objects space rocks, comets etc.. In a sense yes the wooden cube will float in space but not in the water. Even though the cube is in the water there are no forces to make the cube float/move in the water because in space you weight does not matter so no floating. You mentioned "(the mass of water is suspended in air in zero gravity)" sorry my friend but no air can be found in the vacuum of space let alone water well at least not in "mass", since the vacuum is so vast that its takes scattered to a whole new level. Although a good brain twister this event would be pretty unlikely. -.- woops i mean wood (edited).
