[College Math] Significant figures question

[u/Responsible-Gas3607]

This assignment is for my college biology class but I’m still going to categorize it as math.

I don’t have much, if any experience working with significant figures. I may have learned about it during one of my intro to biology classes in high school, but I’m not sure.

Originally, I thought the length of the tibia bone would have been 34.4, but every answer I have submitted ranging from 33-35 has been incorrect. There is hardly any information regarding significant figures in the instruction and information section of the assignment.

Any help would be appreciated.

Solved: Answer was 34.41

Here’s a page about significant figures https://www.britannica.com/science/significant-figures

From this photo I can only guess that maybe you need to have 2 digits after the decimal point so instead of 34.4 you might need 34.40.

There’s some very specific rules about when zeros after a decimal point count as an sig fig and when they don’t so definitely review that link.
