When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.
Any measurement may have two significant digits.
For a quick estimate, you would usually round to one, sometimes to two, significant digits. One significant digit means discarding all digits after the first, i.e., converting them to zero (and rounding the remaining digit up or down as appropriate).
Three: The first two zeros are not significant digits.
