The density of a diamond is 3.51gr/sm3
1 carat is 200 milligrams
What is the volume of a 0.750 carat diamond?
My answer is 0.042
Am i right ?
Thanks 🙏

With some assumptions it is not completely wrong

0.042 of what? Units are (almost) always important part of the answer.

And what is sm3? Do you mean cm³?

Finally, all input data have three significant digits, so your answer should have three significant digits too. 0.042 has only two.
