A wall of length 10m was to be built across an open ground. The height of the wall is 4m and the thickness of the wall is 24cm. If this wall is to be built up with bricks whose dimensions are 24cm×12cm×8cm, how many bricks would be required?

In the figure (not to scale) AB = CD, angle DAP = angle DPA and A,B,C,D are concycli. If angle ADC = 80°, then find angle ACD.
