Molly decides to find the volume of a swimming pool. She measures its length to 3 significant figures, its width to four significant figures, and its height to 2 signficant figures.

A) How many sig figs are in the volume of the pool?

B) How many sig figs should there be in the uncertainty of the volume of the pool?

2. Relevant equations

Volume = length x width x height

3. The attempt at a solution

A) The answer is 2, because it is the least amount of sig figs.

B) I don't know what an uncertainty is, or how to calculate it - maybe someone can explain it or give me a hint and I can try the problem again?

Edit: Maybe there's nothing to calculate - I just remembered there's a rule that says only 1 or 2 sig figs should be present in any error calculation.
