The general brick size is 240* 1 15*53, and the calculation is generally 240* 120*50. Then, the wall is generally built in one step (one step means that the long side of the block is along the direction of the wall, D means that the long side of the block is perpendicular to the direction of the wall, and one step means that one piece of skin is along the long side of the wall, and the other piece is skin.

), so the wall thickness should be calculated according to the long side 240 of the brick. 1 15 wall refers to the wall thickness of 1 15, and the number of bricks required is 1 15/240, that is,12, 180.

The 365 wall should be 360 wall, which is 360/240, which is 3/2.
