Question

State the definition, formula and unit of density as well relative density of an object

Answer 1

DEFINITION -) the mass per unit volume of an object is called its density.
FORMULA -) Mass/Volume
UNIT -) g/cm^3

Answer 2

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. ... Thus a relative density less than one means that the substance floats in water.
