A student has a glass coffee table in their dorm room that they want to stack some of their books on. However they are a little worried about how much pressure the table can withstand at any one point.

If the pile of books has a mass of 12.00 kg, a length of 27.94 cm, a width of 20.32 cm, and
a height of 30.12 cm, how much pressure (N/m2) must the table be able to withstand at any place
where the books are placed ?
