Place the square iron block weighing 77.42 n in the center of the horizontal table top with an area of 1 square meter. The pressure of the iron block on the table top is

V Fe = m / ρ = g / ρ g = 0.001M & sup3;, so s = 0.01 m2
Because it is a horizontal table, the pressure of the object on the table is equal to the gravity of the object
p=F/S=77.42N/0.01㎡=7742Pa
