To determine how many concrete hollow blocks (CHB) are needed for a 16 square meter wall, you first need to know the size of the CHB being used. A standard CHB typically measures 40 cm x 20 cm x 10 cm, which has an area of 0.08 square meters. Dividing the total wall area (16 sq m) by the area of one block (0.08 sq m) gives approximately 200 blocks, not accounting for mortar gaps or wastage. It's advisable to purchase extra blocks to cover any breakage or cutting needs.
