Let’s go step by step.
We are told to use the circle (○) as a unit of weight. That means each ○ weighs 1 unit. We need to count how many ○s are on the left side of each balance scale — because the scale is balanced, that tells us how heavy the object on the right is.

First row:
Left side has 4 circles → so the bottle on the right weighs about
4 ○.
Answer: about
4 ○ heavy
---
Second row:
Left side has 6 circles → so the mug on the right weighs about
6 ○.
Answer: about
6 ○ heavy
---
Third row:
Left side has 4 circles → so the small bottle on the right weighs about
4 ○.
Answer: about
4 ○ heavy
---
Fourth row:
Left side has 9 circles (3 rows: 3 + 3 + 3) → so the teapot on the right weighs about
9 ○.
Answer: about
9 ○ heavy
---
Fifth row:
Left side has 8 circles (top row 4, bottom row 4).
Right side has a box AND 3 circles.
Since the scale is balanced:
Weight of box + 3 ○ = 8 ○
So, weight of box = 8 - 3 =
5 ○
Answer: about
5 ○ heavy
---
Final Answer:
about 4 ○ heavy
about 6 ○ heavy
about 4 ○ heavy
about 9 ○ heavy
about 5 ○ heavy
