A 50-cm³ block of wood is floating partially submerged in water, and a 50-cm³ block of iron is totally submerged in water. Which block has the greater buoyant force on it? A) the wood B) the iron C) Both have the same buoyant force. D) The answer cannot be determined without knowing the densities of the blocks.

The buoyant force is equal to the weight of the fluid displaced. Since the iron block is fully submerged, it displaces more water than the partially submerged wood block, resulting in a greater buoyant force on the iron block.
