SpletAs the other answers (and dmckee's comments) note, yes, if you take the square root of a dimensional quantity then you need to take the square root of the units too: 4 k g = 2 k g 1 2 And no, I can't think of any meaningful physical interpretation for the unit k g 1 2 either. Splet16. jun. 2013 · You can carry all the extra figures through the calculation but only report the final answer in significant figures less than or equal to the least number of significant figures used in the multiplication. In your statement above you are confusing density with mass. The 1.411 figure came from multiplying 1.03 g/cm^3 by the volume in cm^3.
