It is always in three dimensions. To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³).
Density is a measure of how much mass an object has per unit volume. Density is a compound measure because mass and volume can’t be measured in the same units. Objects denser than water sink ...
Density is the mass per unit volume. Density can be found using this equation. Density is sometimes measured in g/cm 3. Make sure that you use units that are consistent with the question in an exam.
