Significant Figures
In a measurement, significant figures consist of the digits definitely known + one estimated digit.
In the example above, measurement A is definitely beyond the 7cm mark and the 0.8cm mark. By looking
carefully, we can estimate that the measurement is halfway between 7.8cm and 7.9cm, so the final
measurement is 7.85cm. This measurement has three significant digits.
How would you record measurement B with three significant digits?
