31780

#### Explanation:

If the correct number of significant figures is not specified, use the same as the question.

$6200 \times 5.125 = 31775$

$31775$ is, to 4 significant figures, $31780$

Significant figures is the same as rounding, if we write a number to $4$ significant figures, then we keep the first $3$ numbers the same and round the $4 r t h$ by looking at the $5 t h$.
