That's Correct!
It's Wrong!
The digits 6, 7, 8, 0, 2, and 4 are all significant because they represent meaningful information about the value.
The trailing zeroes after the decimal point (the zeroes to the right of the decimal point) are also significant in this context. They indicate the precision of the measurement.
So, there are eight significant figures in the number 678.02400.
