The pressure exerted by an object is given by:
where
F is the magnitude of the force
A is the area of the surface perpendicular to the force
In this problem, the force is the weight of the books + the shelf, which is given by
where
m = 262 kg is the total mass
is the acceleration of gravity
Substituting,
The area of the four legs is:
Therefore, the pressure exerted on them is:
