Recall the definition of density, which is the mass of a substance divided by its volume, expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
Understand that when you have a larger piece of the same material, both its mass and volume increase proportionally because you are adding more of the same substance.
Since both mass and volume increase by the same factor, their ratio (mass divided by volume) remains constant.
Therefore, the density of the material does not change when the size of the piece changes; it remains the same regardless of the amount of material.
Conclude that density is an intrinsic property of a material and is independent of the sample size.
