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 13.60 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 ?

If the pile of books has a mass of 11.60 kg, a length of 33.02 cm, a width of 33.02 cm, and
a height of 25.45 cm, how much pressure (N/m2) must the table be able to withstand at any place
where the books are placed ?

    I’m not sure the height of the books is necessary for this problem.

    The point force of the books is 11.60*9.81 = 113.80
    The area the books will cover (in m^2) = .3302 * .3302 = .109
    Pressure = 113.8/.109 = 1044..04 N/m^2

    You figure the answer and then put the books under the glass table.
