Hello everyone today. We have been provided with the following problem. What is the volume of the liquid inside the graduated cylinder? And a And what is the height of the vial in b provide the correct number of significant figures in each measurement? So for a we see that we have our graduated cylinder here and the fluid Gets to about 70, but we don't see it goes beyond that. So if we count it goes 123 and we see where this line intersects The .4 margin, so this is going to be 74 zero. And our units are middle leaders. As designated by this. Middle leaders by the 10. And so this is going to be our measurement for the first portion. For B. We're going to find the same concept, This is going to six. And if we count each individual line, that'll be so 12, It'll be just right at three. So you can say this is 6. and if we look at our units it's going to be centimeters. And so we have the length and the volume recorded significant figures that we counted two. So for the first one we had three significant figures and for the second one we also had three significant figures. And now we have fully completed this problem. I hope this helped. And until next time
