Object magnification after Convex surface

[dimensionless]

I have an object that is surrounded by air and sits a distance U=30 from a convex surface. The convex surface has a radius of R=5. The index of refraction of the refracting media is n=1.33. How do I determine the magnification of the object?

I think, if you find out where the object falls after refraction using the lens maker formula($R_2 = \infty$), you can calculate the magnification using some simple geometry

It is not a thin lense. It is a convex interface between two materials.

My mistake then.
The general equation of refraction at a spherical surface will be
