Retaining Wall Block Calculation
Blocks per Row = Wall Length (in) / Block Length
Rows = Wall Height (in) / Block Height
Total = Blocks per Row × Rows × 1.1 (waste)
计算示例
20 ft long, 3 ft high wall with 12×4 in blocks.
- Blocks per row = 240/12 = 20
- Rows = 36/4 = 9
- Base total = 20 × 9 = 180
- With 10% waste = 198 blocks
