• B. Multiply the mass of the object by its volume
• C. Divide the mass of the object by its volume
• D. Subtract the volume from the mass of the object

Answer: (C)

Verified step by step guidance

1. Recall the definition of density, which is the measure of how much mass is contained in a given volume. The formula for density is given by \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
2. Understand that to find the density of an object, you need two key measurements: the mass of the object and the volume it occupies.
3. Recognize that adding mass and volume together or subtracting volume from mass does not provide a meaningful physical quantity related to density.
4. Also note that multiplying mass by volume results in a unit that does not correspond to density, so this method is incorrect.
5. Therefore, the correct method to determine density is to divide the mass of the object by its volume, using the formula \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
