## Unofficialllyy one year ago A large diamond with a mass of 4289.6 grams was recently discovered in a mine. If the density of the diamond is 3.51 grams over centimeters cubed, what is the volume? Round your answer to the nearest hundredth.

1. Unofficialllyy

$3.51\frac{ g }{ cm^3 }$

3. Unofficialllyy

So now I have $3.51\frac{ g }{ cm^3 }=\frac{ 4289.6 }{ volume }$

4. triciaal

Round your answer to the nearest hundredth. calculate to 3 decimal places. look at the 3rd place if 5 or more add 1 to the 2nd decimal place. if the 3rd decimal place is less than 5 just drop it.

5. Unofficialllyy

1221.9 cm^3

6. triciaal

correct unit of measure for mass is grams so in the formula the g's will cancel out

8. Unofficialllyy

I'm confused

Here's an equation to help you set up the problem.

sorry for the cruddy writing, i'm using my mouse lol

12. Unofficialllyy

No worries, now I multiply by 4289.6 on both sides right?

13. anonymous

You plug in the values you're given into the equation.

14. anonymous

No, you multiply the volume on both sides.

15. anonymous

So it'll look like this:

16. anonymous

|dw:1440363459131:dw|

17. anonymous

Then you divide both sides by 3.51 to get your answer.

18. Unofficialllyy

I got it, the answer is 1222.1082621083

19. anonymous

Sounds right to me. Remember your units!!

20. Unofficialllyy

And the closest to that from my answer choices is 1221.9 cm^3

21. anonymous

That sounds like a reasonable answer.

22. triciaal

@anitasonia98 all that was already done!!

23. anonymous

@triciaal Unofficiallyyyy was confused, so I was clarifying.

24. triciaal

you should find out what he/she was confused about. you are incorrect because the directions said to the nearest hundredth. means to 2 decimal places. now both of you should review the thread.
