Answer:
C. 20 cm^3
Step-by-step explanation:
Using the equation D=m/v, you would plug in the given mass (227 g) into m and the given density of lead (11.35 g/cm^3). Solving for v=m/D, we find the answer to be 20 cm^3.
Also, you could cancel out all the answers except C because it is the only one in units of volume (1 cm^3 = 1 mL).
