Answer:

He requires 1 gram of mass.

Step-by-step explanation:

The density is defined as:

$\rho = (m)/(V)$ (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.

$m = \rho \cdot V$ (2)

m = (3.00g/cm^(3))(3.00cm^(3))

m = 1g

Hence, he requires 1 gram of mass.
