Solution

0.0006032 m2 has four significant figures.

Explanation:

In numbers less than one, any zeros between the decimal point and the first non-zero digit are not considered significant; they merely set the decimal place. Therefore, the initial three zeros are not significant. However, the digits 6, 0, 3, and 2 are all significant, including the zero, because it lies between two non-zero digits, indicating precision in the measurement.
