volume before
(blank 1)
volume after
(blank 2)

Explanation:

Step1: Determine Volume Before

The graduated cylinder scale is 0.2 mL per division. Before adding the object, the liquid level is at 5 mL? Wait, no, let's count the divisions. From the first cylinder, the meniscus is at 5 mL? Wait, no, let's see: each major mark (like 4,5,6) has how many divisions? Let's check the first cylinder: between 4 and 5, how many lines? Wait, the scale is 0.2 mL. So from 4 to 5, there are 5 divisions (since 1 mL / 0.2 mL per division = 5). Wait, the first cylinder: the liquid level is at 5 mL? Wait, no, looking at the first cylinder, the meniscus is at 5 mL? Wait, no, let's count the divisions. Wait, the first cylinder: the level is at 5 mL? Wait, no, maybe I misread. Wait, the first cylinder: the lines are at 1,2,3,4,5,6. Each major mark (e.g., 4 to 5) has 5 small divisions (since 0.2 mL per division, 5*0.2=1 mL). So the first cylinder (Volume Before) has the liquid at 5 mL? Wait, no, wait: the first cylinder's liquid is at 5 mL? Wait, no, let's see: the first cylinder, the meniscus is at 5 mL? Wait, no, maybe the first cylinder: from the bottom, the first major mark is 1, then 2,3,4,5,6. The liquid in the first cylinder is at 5 mL? Wait, no, wait the scale is 0.2 mL. Wait, maybe the first cylinder: the level is at 5.0 mL? No, wait, let's look again. Wait, the first cylinder: the liquid is at 5 mL? Wait, no, the second cylinder (after adding the object) is at 5.8 mL? Wait, no, let's do it properly.

Wait, the graduated cylinder has a scale of 0.2 mL per division. So each small line is 0.2 mL. Let's look at the first cylinder (Volume Before): the meniscus is at 5 mL? Wait, no, between 4 and 5, how many divisions? Wait, from 4 to 5, there are 5 divisions (since 1 mL / 0.2 mL per division = 5). So the first cylinder: the liquid is at 5 mL? Wait, no, the first cylinder's liquid is at 5.0 mL? Wait, no, maybe the first cylinder: the level is at 5.0 mL? Wait, no, let's count the divisions. Wait, the first cylinder: the lines are at 1,2,3,4,5,6. The liquid in the first cylinder is at 5 mL? Wait, no, the second cylinder (after adding the object) is at 5.8 mL? Wait, no, let's see: the first cylinder (Volume Before) has the liquid at 5.0 mL? Wait, no, maybe I'm wrong. Wait, the first cylinder: the meniscus is at 5 mL? Wait, no, the first cylinder's liquid is at 5.0 mL? Wait, no, let's check the second cylinder. The second cylinder (Volume After) has the liquid at 5.8 mL? Wait, no, let's count the divisions. From 5 to 6, there are 5 divisions (0.2 mL each). So the second cylinder: the liquid is at 5 + 4*0.2 = 5.8 mL? Wait, no, 5 + 4*0.2 = 5.8? Wait, 0.2*4=0.8, so 5.8 mL. And the first cylinder (Volume Before) is at 5.0 mL? Wait, no, the first cylinder: the liquid is at 5.0 mL? Wait, no, the first cylinder's meniscus is at 5 mL? Wait, maybe the first cylinder is at 5.0 mL and the second at 5.8 mL? Wait, no, let's re-express.

Wait, the scale is 0.2 mL per division. So each small line is 0.2 mL. Let's look at the first cylinder (Volume Before): the liquid level is at 5 mL? Wait, no, between 4 and 5, how many lines? Let's see, the first cylinder: from 4 to 5, there are 5 lines (since 1 mL / 0.2 mL per line = 5). So the first cylinder's liquid is at 5 mL? Wait, no, the first cylinder's liquid is at 5.0 mL? Wait, maybe the first cylinder is at 5.0 mL (Volume Before) and the second at 5.8 mL (Volume After). Wait, let's confirm:

For Volume Before (first cylinder):

The meniscus is at the 5 mL mark? Wait, no, the first cylinder's liquid is at 5.0 mL? Wait, maybe the first cylinder has the liquid at 5.0 mL (since the scale is 0.2 mL, and the meniscus is at the 5 mL line). Wait, no, maybe the first cylinder is at 5.0 mL and the second at 5.8 mL. Let's check the second cylinder: from 5 to 6, there are 5 divisions (0.2 mL each). So the second cylinder's liquid is at 5 + 4*0.2 = 5.8 mL (since the meniscus is 4 divisions above 5 mL). And the first cylinder's liquid is at 5.0 mL (meniscus at 5 mL, 0 divisions above 5 mL).

Step2: Determine Volume After

As above, the second cylinder (Volume After) has the liquid at 5.8 mL.

Answer:

Blank 1: 5.0 mL
Blank 2: 5.8 mL
