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.

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 answer will depend on the orientation of the blocks. It will be between 13 and 25.
Depends entirely on the size of the individual blocks !

The answer depends on the volume of the hollow.

There are 10 blocks in a square meter

More info needed. There are so many sizes of concrete blocks. Different industries use different sizes. 6 x 2 x 10 is just ONE size.
