When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.
The number 0.30 has two significant figures.
The number 3,072 has 4 significant figures.
