The number of significant figures in 0.000040027 m2 is 5.

If the number is less than one, then the zeroes on the right of the decimal point (but left to the first non-zero) are insignificant. Hence, all four zeroes appearing before 4 are not significant figure. All zero between two non-zero digit are always significant. Hence, the remaining five digits are significant figures.
