For blocks that are 450mm x 225mm , you will need 9.88 blocks per square metre.
are these concrete blocks and allowing for mortar. 12.5 per square metre, 62.5 per cubic metre with mortar
I understand such blocks come in different sizes.

20.66 blocks per m2 when laid flat (block size 100 x 440 x 215)
The answer will depend on the size of the blocks.

The number of breeze blocks per square meter will depend on the size of the breeze block. Typically, a standard breeze block measures 440mm x 215mm, so to cover 1 square meter with these blocks, you would need approximately 20 blocks. However, for accurate calculations, it's best to refer to the specific dimensions of the breeze block you will be using.
The answer will depend on the orientation of the blocks. It will be between 13 and 25.
