Answer:
10 cm^3
which agrees with the second option listed
Step-by-step explanation:
We start by finding the number of significant figures of each of the values to be multiplied:
0.020 cm has TWO significant figures
50 cm has ONE significant figure
11.1 cm has THREE significant figures
So, recalling the rule for multiplication: "The result of a product of quantities should have the same number of significant figures as the measured value with the least number of significant figures", we conclude that whatever value we get for answer, it should be rounded to ONE significant figure, which is our least number of significant figures for this case>
Performing the indicated operation we get mathematically : 11.1 cm^3, which rounded to one significant figure becomes: 10 cm^3
