There is no general rule. There are different formulae for simple figures like a sphere, a cone and a cylinder. Other figures have yet other and more complex formulae.
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
The main disadvantage is that in may cases the level of precision is limited to three significant figures.
There are 2 because of the leading zeros rule. Zeros at the beginning of a number are never significant.
The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)
