Question

Define density.give its unit

Answer 1

A material's density is defined as its mass per unit volume. It is, essentially, a measuremement of how tightly matter is crammed together. The principle of density was discovered by the Greek scientist Archimedes.To calculate the density (usually represented by the Greek letter "rho") of an object, take the mass (m) and divide by the volume (v):rho = m / vThe SI unit of density is kilogram per cubic meter (kg/m3)
