IF you mean "what is 102.1604043 mm^3 to the nearest

**cubic**mm", not "mm", then the answer is 102 cubic mm., of course. 102.1... is**below**102.5 so it is nearer 102 mm than 103 mm.

If you mean to take the cube**root**of 102.1604043 and then ask "what is it to the nearest mm.", it is easy to use a calculator to see that $\displaystyle \sqrt[3]{102.1604032}= 4.674777$ which is larger than 4.5 mm and so is 5 mm, to the nearest mm. - Jan 20th 2013, 12:36 PMashicusRe: whats 102.1604043mm3 (cubed) to the nearest mm?
