Final answer:
Density is obtained by dividing the mass of an object by its volume. For the given object with a mass of 650 g and dimensions that yield a volume of 260 cm³, it has a density of 2.5 g/cm³.
Step-by-step explanation:
Calculating Density
The concept in question pertains to density, which is a measure of how much mass is contained in a given volume. Density is calculated using the formula Density = Mass / Volume. In the provided problem, you are given the mass (650 g) and dimensions of an object (5.0 cm x 8.0 cm x 6.5 cm), which can be used to find its volume.
The volume of a rectangular object is found by multiplying its length by its width and its height. So, for the object in question, its volume would be 5.0 cm × 8.0 cm × 6.5 cm, which equals 260 cm³. To find the density, divide the mass by the volume, so the density is 650 g / 260 cm³, which calculates to a density of 2.5 g/cm³.
