Q. Explain density?
Answer:-
Density is a physical characteristic also is a measure of mass per unit of volume of a material or substance. It is a dimension of the amount of matter in a given volume of something.
The higher an object's density means the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser thing (such as iron) will have less volume than an equal mass of some less dense substance (such as water).
The density, ?, of an object is given by the ratio of the object's mass, m, and volume, V, according to the equation ? = m/V. What is the density of a cube that is 1.2 cm on each s
