To solve the problem, we need to count the place value blocks in each row and determine the total number of blocks. Place value blocks typically represent:
-
Cubes (thousands): Each cube represents 1,000.
-
Flats (hundreds): Each flat represents 100.
-
Rods (tens): Each rod represents 10.
-
Units (ones): Each unit represents 1.
Let's analyze each row step by step:
---
Row 1:
-
Cubes (thousands): 3 cubes → \(3 \times 1,000 = 3,000\)
-
Flats (hundreds): 4 flats → \(4 \times 100 = 400\)
-
Rods (tens): 6 rods → \(6 \times 10 = 60\)
-
Units (ones): 1 unit → \(1 \times 1 = 1\)
Total for Row 1:
\[
3,000 + 400 + 60 + 1 = 3,461
\]
---
Row 2:
-
Cubes (thousands): 2 cubes → \(2 \times 1,000 = 2,000\)
-
Flats (hundreds): 5 flats → \(5 \times 100 = 500\)
-
Rods (tens): 8 rods → \(8 \times 10 = 80\)
-
Units (ones): 7 units → \(7 \times 1 = 7\)
Total for Row 2:
\[
2,000 + 500 + 80 + 7 = 2,587
\]
---
Row 3:
-
Cubes (thousands): 1 cube → \(1 \times 1,000 = 1,000\)
-
Flats (hundreds): 7 flats → \(7 \times 100 = 700\)
-
Rods (tens): 9 rods → \(9 \times 10 = 90\)
-
Units (ones): 5 units → \(5 \times 1 = 5\)
Total for Row 3:
\[
1,000 + 700 + 90 + 5 = 1,795
\]
---
Row 4:
-
Cubes (thousands): 5 cubes → \(5 \times 1,000 = 5,000\)
-
Flats (hundreds): 0 flats → \(0 \times 100 = 0\)
-
Rods (tens): 7 rods → \(7 \times 10 = 70\)
-
Units (ones): 0 units → \(0 \times 1 = 0\)
Total for Row 4:
\[
5,000 + 0 + 70 + 0 = 5,070
\]
---
Row 5:
-
Cubes (thousands): 4 cubes → \(4 \times 1,000 = 4,000\)
-
Flats (hundreds): 6 flats → \(6 \times 100 = 600\)
-
Rods (tens): 10 rods → \(10 \times 10 = 100\)
-
Units (ones): 3 units → \(3 \times 1 = 3\)
Total for Row 5:
\[
4,000 + 600 + 100 + 3 = 4,703
\]
---
Final Answers:
\[
\boxed{3461, 2587, 1795, 5070, 4703}
\]
