Final answer:
To find volume using the density equation, rearrange the formula to volume (v) = mass (m) / density (d). When an object's mass and density are known and its volume needs to be computed, this formula is utilized.
Step-by-step explanation:
The student's question is about solving for volume using the density equation. Density is usually represented by the formula density (d) = mass (m) / volume (v). When solving for volume, we rearrange the formula to get volume (v) = mass (m) / density (d). This is because density is a measure of how much mass is contained in a given volume. The rearranged density equation is useful when you know the mass of an object and its density and want to calculate its volume.
