How many significant figures are needed when multiplying two numbers?

It depends on the number of significant figures from two numbers you are multiplying. But when multiplying you use the same number of significant figures from the numbers you are multiplying with the LEAST number of significant figures.
Example:
92,873.239 * 2 = 200,000 (because the number 2 has only 1 significant figure even tho 92,873.239 has 8 significant figures your answer still only has 1 significant figure)

All jobs.
Where were Arabic numerals invented?
The Arabic people needed a numeral system and made figures, numbers. They based their system off of zero and also made negatives that the Roman numerals lack.
Why is the FOIL method not needed when multiplying two binomials?
It is only not needed if you know of another method. If FOIL is the only way you know to multiply two binomials, then it is definitely needed.

How many significant figures are in temperatures?
Temperatures are typically measured with 1-2 significant figures, as precision beyond that is usually not needed for everyday purposes. However, in scientific contexts, temperatures can be measured with more significant figures depending on the sensitivity of the measuring instrument.
What is 2700000 in scientific notation?
2.7 X 106 ======= Zeros are superfluous unless needed for significant figures.
What is the rule about significant figures?
The rule for significant figures is that all non-zero digits are considered significant. Zeros between non-zero digits are significant, as well as trailing zeros after a decimal point. Leading zeros (zeros to the left of the first non-zero digit) are not considered significant.
Why can't we write numbers with as many significant figures as we want?
Writing numbers with unlimited significant figures would be impractical and unnecessary in most cases. Additionally, precision in measurements is limited by the precision of the measuring instrument, and including extra significant figures can give a false sense of accuracy. It's important to use an appropriate number of significant figures to convey the level of precision needed for a particular calculation or measurement.
How many feet are in 1.08 meters?
There are 5.9 ft in 1.08 meters. 1 metre = 3.2808399 feet 1.08 metres = 3.54 feet 1.08 meters has three significant figures so the answer has to be three significant figures. An answer can not be more accurate/precise than the starting figure. 3.2808399 is eight significant figures. The instrument needed to get a measurement accurate to that degree would be very very rare if it exists at all.
