Question

Students perform an investigation using density to determine what kind of wood an oval-shaped block is made of.

One student attaches a lead cube to an oval-shaped piece of wood and submerges them in water, as shown in the
diagram. The lead cube keeps the wood from floating. When the wood is underwater, the water level reads 47
milliliters.

Answer 1

Density is responsible for why the wood block floats and the brass block sinks in water.

Step-by-step explanation:

The answer to the student's question lies in the concept of density. Density is the mass of an object divided by its volume. In the given scenario, the wood block floats on the water's surface because its density is lower than that of water. The brass block on the other hand sinks because its density is higher than that of water.
