If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar.

The density of an object or substance is its mass divided by its volume: Density = Mass ÷ Volume. The units of density depend on the units used for mass and volume, but are usually: g/cm³ (if ...

If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low density. Mass is the amount of matter in an object. Volume is how much space the object takes up.

I had never before been told I had dense breasts, never been told that breast density increased my risk for breast cancer, never been told that breast density greatly reduces the effectiveness of ...
