Question

What is density

Answer 1

Solution -
Density -

A material's density is defined as its mass per unit volume. It is, essentially, a measurement 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 "ρ") of an object, take the mass (m) and divide by the volume (v):

ρ = m / v

The SI unit of density is kilogram per cubic meter (kg/m³).
