Let’s solve each problem one by one.
We are told that
1 block = 1 lb.
Each scale is balanced, which means the weight on the left side equals the weight on the right side.
---
1. Toolkit
Left side: 2 blocks → 2 lbs
So, toolkit weighs
2 lbs
---
2. Scooter
Left side: Let’s count the blocks.
Top row: 1 block
Middle row: 2 blocks
Bottom row: 3 blocks
Total = 1 + 2 + 3 =
6 blocks → 6 lbs
So, scooter weighs
6 lbs
---
3. Desk
Left side: 3 blocks → 3 lbs
So, desk weighs
3 lbs
---
4. Coffee
Left side: 1 block → 1 lb
So, coffee weighs
1 lb
---
5. Cake
Left side: Count the blocks.
Top row: 2 blocks
Bottom row: 3 blocks
Total = 2 + 3 =
5 blocks → 5 lbs
So, cake weighs
5 lbs
---
6. Building
Left side: Count the blocks.
Top row: 3 blocks
Bottom row: 4 blocks
Total = 3 + 4 =
7 blocks → 7 lbs
So, building weighs
7 lbs
---
Final Answer:
The toolkit weighs
2 lbs.
The scooter weighs
6 lbs.
The desk weighs
3 lbs.
The coffee weighs
1 lb.
The cake weighs
5 lbs.
The building weighs
