blocks = wall sq ft block sq ft. If you’re using a standard 8″ x 8″ x 16″ block, find the number of blocks needed by dividing the wall square footage by 0.89. blocks = wall sq ft 0.89. We recommend adding 5%-10% additional blocks to account for broken blocks or blocks that need to be cut for the edges.
Jul 30, 2024 · If you use a standard 16" x 8" block, the area of a single block is 128 square inches, and you will need 563 concrete blocks, as 500 ft² / 128 in² = 72,000 in² / 128 in² = 562.5 (rounding up to the nearest whole number).

Aug 21, 2023 · Wall Area: 10 feet (height) × 20 feet (length) = 200 square feet. Block Area: Each block covers approximately 1.125 square feet (including the mortar joint). Number of Blocks: 200 square feet / 1.125 square feet per block ≈ 178 blocks. Waste Factor: Adding 5% for waste is approximately 187 blocks.
Block Area = 8 inches × 16 inches = 128 square inches. Calculate the number of blocks: Number of Blocks = Wall Area / Block Area. Number of Blocks = 11,520 square inches / 128 square inches = 90 blocks. Therefore, for your retaining wall project, you would need approximately 90 concrete blocks. 4.
