Because friction depends only on cofficient of friction and roughness of the surfaces and it is independent of the area b/w the surfaces.
Tejaswin Gumber
Friction is a microscopic constant and so macroscopic level area does not matter.
But area would matter if the object we''re putting under study was microscopic, which isn''t in our case.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
