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.

There are 60 bricks per m2. (59.26 to be precise).
Area of each block = 450 mm x 225 mm = 0.45 m x 0.225 m = 0.10125 m2 Area to be covere = 170 m2 So, minimum number of blocks required = 170/0.10125 = 1679.01 = 1680. However, this assumes that there is virtuall no wastage and, in real life, you should allow 5-7% extra.
