A wooden block of mass

12\,\text{kg}

has dimensions

30\,\text{cm}\times20\,\text{cm}\times5\,\text{cm}

. (Take

g = 9.8\,\text{m/s}^2

.) (i) Calculate the pressure exerted by the block when it rests on the face measuring

30\,\text{cm}\times20\,\text{cm}

. (ii) Calculate the pressure when it rests on the face measuring

20\,\text{cm}\times5\,\text{cm}

. State which orientation produces the greater pressure.
