The number of concrete hollow blocks in 1 square meter depends on the size of the blocks. For example, if the blocks are 20cm x 20cm x 40cm, which is a common size, you would need 25 blocks to cover 1 square meter (assuming no gaps or mortar). This calculation is based on the fact that each block covers 0.04 square meters (0.2m x 0.2m) of surface area. It's important to consider the dimensions of the blocks and the desired layout to determine the exact number needed.

It depends on the size of the concrete blocks
To determine the number of concrete hollow blocks needed for a 7m x 10m wall, you first need to calculate the wall area. The total area is 7m x 10m = 70 square meters. If a standard concrete hollow block measures approximately 0.4m x 0.2m (0.08 square meters), you would divide the total area by the area of one block: 70 ÷ 0.08 = 875 blocks. Therefore, you would need approximately 875 concrete hollow blocks to cover that area, not accounting for windows, doors, or waste.

370 8 x 8 concrete blocks equal approximately 164 square feet.
I understand such blocks come in different sizes.
are these concrete blocks and allowing for mortar. 12.5 per square metre, 62.5 per cubic metre with mortar
The number of concrete blocks per square meter depends on the size of the blocks. A standard concrete block typically measures 400 mm x 200 mm x 200 mm. Given these dimensions, approximately 12.5 blocks fit in one square meter (1 m² = 10,000 cm², and each block occupies 800 cm²). If using different sizes, the calculation would need to be adjusted accordingly.
The answer will depend on the orientation of the blocks. It will be between 13 and 25.
To calculate the number of hollow blocks needed for a 70,000 square meter wall at a height of 7 feet, first convert the height to meters (7 feet ≈ 2.13 meters). The total wall area would be 70,000 m² × 2.13 m = 149,100 m². Assuming an average hollow block size of 0.4 m², you would need approximately 372,750 blocks (149,100 m² ÷ 0.4 m²). Adjust for waste and mortar gaps as necessary.
