What is density and volume |
| Answer» SITY, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin LETTER D can also be used. Mathematically, density is DEFINED as mass divided by volume: {\displaystyle \rho ={\frac {m}{V}}} where ρ is the density, m is the mass, and V is the volume.Volume is the quantity of three-dimensional SPACE enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the CUBIC metre. | |
