A solid rectangular wooden block of weight 600N has length 30cm, breadth 20cm and height 10cm. The block is placed on a level laboratory table in two different orientations.
(i) Calculate the pressure exerted on the table when the block rests on its largest face (length × breadth). Express your answer in pascals.
(ii) The block is now turned so that it rests on its smallest face (breadth × height). Calculate the new pressure on the table.
(iii) By what factor has the pressure changed between the two orientations? State which orientation is likely to leave a deeper mark on a soft wax sheet kept on the table and give a brief reason.
