I understand such blocks come in different sizes.

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.

The answer will depend on the size of the blocks.
60 blocks make a metre square
To calculate the number of 140mm blocks per square meter, we first need to convert the dimensions to the same unit. Since 1 meter is equal to 1000mm, we can calculate the area of a square meter in square millimeters (1000mm x 1000mm). Next, we divide the area of a square meter by the area of a single 140mm block (140mm x 140mm) to determine how many blocks can fit in a square meter. This calculation would yield the number of 140mm blocks per square meter.

The answer depends on the volume of the hollow.
