6.8000

Explanation:

The "ten-thousandth" is the fourth place behind the decimal. Rounding up from the 7 in the fifth place rolls up the rest of the digits into an '8' in the tenths spot.

However, because you are round from the hundred-thousandth place you must retain the zeroes up to the ten-thousandth place to indicate that they are significant, and should not be discarded.
