Answer:
mass = density × volume
Step-by-step explanation:
The density of a material is calculated using its mass and the amount of space occupied by it. Mathematically, it is given by :
..............(1)
Where
is the symbol of density
The SI unit of density is
or
.
From equation (1) we can calculate the mass of the substance as :

or
mass = density × volume
Hence, this is the required solution.
