Hint: Limiting friction is the maximum amount of friction that can be produced between two static surfaces. Only the normal force and surface of the body are responsible for the limiting friction between any two surfaces.

$f = \mu N$
Where $f$ is the limiting friction,
$\mu$ is the coefficient of limiting friction,
And $N$ is the normal force acting on the body.
The limiting friction will depend on the nature of the two surfaces because $\mu$ depends on the two surfaces. As we can see in the formula of limiting friction, it depends on the normal reaction, and as the normal reaction is equal to its weight, therefore the limiting friction does not depend on height or its dimensions. It only depends on the surface of the two bodies.
