I have a question about how to read the correct significant figures from an 10mL and 100mL test tube. The 10mL test tube is incrimented by .1. So for example if i measure something that was 8mL at the meniscus level would it be correct to state this result as 8.000mL , 8.00mL, 8.0mL, or 8mL? I'm confused.

I think you should go with 8.00 mL.

You know that it's somewhere between 8.0 and 8.1 (because it goes up by those increments), so there are your first two significant figures. Then, the third one is an estimate.
