Exactly 10 cmd. Exactly 15Explanation / Answer
you have not mentioned the tables however I am giving you a general idea about significant figure
Determine how many significant figures, within the numbers you are multiplying or dividing, contains the least amount of significant figures. For example if you were multiplying 40.6 by 19.14, the number with the least amount of significant figures would be 40.6 with 3 significant figures verses the 4 significants in 19.14.
Round your solution to the amount of significant figures you discovered in step 2. If we were to multiply 40.6 by 19.14 you would get a product of 777.084. Since the least amount of significant figures we discovered was 3, we would round the product to three significant figures.
