Quizplus · Accepted Answer

The density of a material is its mass per unit volume. We know that the blocks are in water, which has a known density of 1 g/cm^3. We can estimate the density of each block by seeing how much it sinks in water. Block 3 appears to sink the most, indicating that it has the highest density. Therefore, block 3 is the densest material in this figure.
