Let’s solve each problem step by step. We’re counting blocks that represent place value:
-
Big flat squares = 100 blocks each (hundreds)
-
Long rods = 10 blocks each (tens)
-
Small cubes = 1 block each (ones)
We’ll add them up for each set.

Problem 1:
- 1 big square → 100
- 3 rods → 3 × 10 = 30
- 0 small cubes → 0
Total: 100 + 30 =
130
---
Problem 2:
- 2 big squares → 2 × 100 = 200
- 0 rods → 0
- 4 small cubes → 4
Total: 200 + 4 =
204
---
Problem 3:
- 1 big square → 100
- 4 rods → 4 × 10 = 40
- 6 small cubes → 6
Total: 100 + 40 + 6 =
146
---
Problem 4:
- 2 big squares → 200
- 1 rod → 10
- 2 small cubes → 2
Total: 200 + 10 + 2 =
212
---
Problem 5:
- 3 big squares → 300
- 0 rods → 0
- 5 small cubes → 5
Total: 300 + 5 =
305
---
Problem 6:
- 2 big squares → 200
- 6 rods → 6 × 10 = 60
- 0 small cubes → 0
Total: 200 + 60 =
260
---
Problem 7:
- 4 big squares → 400
- 4 rods → 40
- 5 small cubes → 5
Total: 400 + 40 + 5 =
445
---
Problem 8:
- 5 big squares → 500
- 2 rods → 20
- 3 small cubes → 3
Total: 500 + 20 + 3 =
523
---
Final Answer:
1) 130
2) 204
3) 146
4) 212
5) 305
6) 260
7) 445
8) 523
