A block of wood half as dense as water floats with half its volume above water.A piece of iron is then tied on top so the wood floats with only 1/4 its volume above the surface.If the wood and iron are turned over so that the iron is submerged beneath the wood,then the volume of wood above the water surface will be
A)more than 1/4.

When the iron is submerged beneath the wood, the overall buoyancy of the system remains the same, but the distribution of weight changes. The wood will displace the same amount of water as before to balance the weight of the iron, resulting in more than 1/4 of the wood's volume above the water.
