The answer will depend on the orientation of the blocks. It will be between 13 and 25.
What sort of blocks? Childrens' building blocks? If so, how big is each block?
10 cm = 0.1 meter 20 cm = 0.2 meter Each block covers (0.1 x 0.2) = 0.02 square meter. To cover 12 square meters, you need 12/0.02 = 600 blocks.
Depends on the linear dimensions of both the slabs and the ground.

1x1 meter is a square meter.
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.
600mm is 0.6m, and 450mm is 0.45m, so one flag is 0.27 sq metre. Therefore 4 flags to the square metre
