Final answer:
To measure the mass, volume, and density of various objects, you can use an analytical balance to measure mass, measure volume indirectly through length measurements or by determining the displacement of water, and calculate density by dividing mass by volume.
Step-by-step explanation:
The most straightforward method of determining the density of an object involves finding its mass and volume separately, and then dividing the mass by the volume. Mass can be measured using an analytical balance, while volume can be measured indirectly through length measurements or by determining the displacement of water. For example, the volume of a regular solid can be calculated using its geometric parameters, such as length, width, and height.
