Marshmallows vary in density. They are not a pure substance. As they contain air bubbles their density can be altered merely by squeezing them as can their volume but their mass would be the same even if smashed into pieces.
The marshmallow's physical dimensions would change.

When mass and volume change what happens to the density?
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
How do you change density?
To change density there are three ways. You can change the shape, mass or volume of the object
Why density does not change with volume?
Density is how tightly packed the matter in a substance is. Therefore, how much space it takes up (volume) will not affect this.
What is the density of a nickel if it were sawed in half?
It is unchanged. The density is the mass divided by the volume, and as both of these numbers are halved the density does not change.
Would the density of a block change if you cut it in half explain your answer mathematical reasoning and the word ratio?
No it will not change. Density is mass divided by volume. Since the ratio of the mass is 1/2 and the volume ratio is 1/2, there is no change. The same holds true no matter how you cut the block, as both mass and volume change proportionally the same.
