1) The brick when placed such that the dimensions of the surface are 60×40cm^2....
2) The lowest area will be 0.04 m^2.
3) Pressure(P) = (Force acting normally) / (Area occupied).........
Therefore pressure is inversely proportional to area .So when area is the smallest pressure is the greatest or most and vice versa......Thus we can say the maximum pressure will be exerted with the brick having the smallest or minimum area and thus the brick with smallest area is the one height by breadth (40×10 cm^2) and so it will exert the max pressure.......
