Answer:
He requires 1 gram of mass.
Explanation:
The density is defined as:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where m is the mass and V is the volume.
Then, m can be isolated from equation 1 in order to determine the mass.
[tex]m = \rho \cdot V[/tex] (2)
[tex]m = (3.00g/cm^{3})(3.00cm^{3})[/tex]
[tex]m = 1g[/tex]
Hence, he requires 1 gram of mass.
