3 significant figures means three digits from the leftmost digit that isn't a zero. So 3.8754 will get rounded to 3.88. Another example to demonstrate the non-zero part of significant figures would be rounding 0.0089643 to 3 significant figures. You would get 0.00896 because you go from the leftmost digit that isn't a zero, in this case it is the 8. With numbers that have zeros in them that are not the leftmost digit get treated in the same way. 8065 rounded to 3 significant figures will be 8070. Treat the zeros as ordinary digits if they are not the leftmost digits.
