1. The problem statement, all variables and given/known data The side of a cube is 12.04 cm. Write it's surface area rounded off to the appropriate significant figures. 2. Relevant equations Surface area=6 x side^2 For multiplying, the answer should be written with the number of significant figures equal to the least number of significant available in the numbers in the product. 3. The attempt at a solution Upon multiplying, the actual answer is 869.7696. In my book, it was given that since 12.04 has four significant figures, we must round off 869.7696 to four significant figures and hence, the answer is 869.8. My doubt is that, since there is a 6 present in the product that has only one significant number, the answer should be expressed with only one significant number and so, the answer should be 900. Am I right in saying that?
