738.928 cubic cm
The (incredibly simple) equation is 6800 grams / 8.96 g/cm3
This ain't exactly rocket science...

Divide the mass of copper you have by its density.
6.8 kg is 6,800 grams.
6.800 g divided by 8.96 g/cm cubed = 758.93 cm cubed.
If you end up with a solid cube of copper, each side will be just over 9 cm in length. That's a nice chunk of copper.

Use conversion factors.
6.80kg copper = 6800g
Since the density is 8.96g/cm^3, divide 6800 by the density to eliminate grams and you will be left with the answer in cm^3. Don't forget you significant digits.
And don't listen to the moron above me because you need to convert kg to grams before you divide. What an idiot!

1 of melted copper liter =1000 cm^3, so 1liter has a weight of 8960g =8.96kg
and 6.8 kg has a volume of 6.8/8.96 =0.759 l = 759 cm^3
with a side of 8.32 cm

How about you just divide the two damn numbers? Dimension of the answer (cm cubed) should be enough of a hint, really.
