78.24 since you had two decimal places in the multiplier you'll have two in the answer.
The product of 24m and 3.26m is 78.24m². Since both values have two significant figures, the answer should be rounded to two significant figures as well, giving 78m².
Rounding after each step in a calculation helps prevent errors from accumulating. It ensures that the final result is based on the correct number of significant figures and maintains accuracy throughout the process. This practice helps improve the precision of the calculated result.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
significant figures in the original numbers used in the calculation. This means the final answer should be rounded to the same number of significant figures as the number with the least amount of significant figures.
32.2
That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.
63.6615

It might have been possible to answer the question if the "following" multiplication had followed. But since you did not bother to make sure that it did, I cannot provide a more useful answer.
There should be 3.
6 of them.
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The calculation of 28.79 divided by 128.32 results in 0.2234.
7.34
4 significant figures.
which is the correct product of the significant figures 3.278 and 4.23.
4,566 to 3 significant figures is 4,570.
