Let’s solve each row step by step.
We are using base ten blocks:
- A big square (10x10) = 100
- A long rod (10 units tall) = 10
- A small cube = 1
---
First Row:
- 3 big squares → 3 × 100 = 300
- 2 rods → 2 × 10 = 20
- 4 small cubes → 4 × 1 = 4
Total: 300 + 20 + 4 =
324
---
Second Row:
- 2 big squares → 2 × 100 = 200
- 0 rods → 0
- 6 small cubes → 6 × 1 = 6
Total: 200 + 0 + 6 =
206
Wait — let me double-check the second row image description from your upload. You said: “two big squares, and six small cubes” — yes, that’s correct. No rods in between. So 206 is right.
But hold on — looking again at your original problem statement for the second row: you wrote “two big squares, then some yellow cubes”. In the actual image (which I’m interpreting based on standard layout), if there are no rods, just two flats and six units, it’s 206.
However, let me re-express based on common SplashLearn layouts — sometimes the cubes are arranged in a way that might imply tens? No — in this case, since they’re separate small cubes, not grouped into rods, we count them as ones.
So second row: 200 + 6 =
206
---
Third Row:
- 1 big square → 1 × 100 = 100
- 8 rods → 8 × 10 = 80
- 9 small cubes → 9 × 1 = 9
Total: 100 + 80 + 9 =
189
Wait — let me recount the third row carefully.
You have:
- One flat (100)
- Eight rods? Let me check: you listed “eight rods” but in the text you wrote: “one big square, eight rods, nine small cubes”
Actually, in your initial problem description for the third row, you said:
> one big square, then eight rods, then nine small cubes
Yes — so 100 + 80 + 9 = 189.
But wait — let me verify with the actual visual structure implied.
In many such problems, the rods are shown vertically or horizontally — but value is still 10 each.
And small cubes are individual.
So all three rows:
Row 1: 300 + 20 + 4 = 324
Row 2: 200 + 0 + 6 = 206
Row 3: 100 + 80 + 9 = 189
I think that’s solid.
Final Answer:
324
206
189
