How many concrete hollowblocks can be used for 7m x 10 meters?

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.
