ray plane intersection

I am still confused about how ray plane intersection works for 3D objects like a missile and building or walking into a solid object.
I am needed it for a computer game but i prefer to understand the mathmatics first.
I think the issue is that I need an example with real coodinates.

How are your rays and planes represented?

Not what do they represent, how are they represented?
Are they represented as parametric equations?
As a pair of points and a triple of non-colinear points?
As a point and a vector and a point and a normal vector?
As a linear equation and a determinant equation?

both will be points. One will be a cuboid with points  to test (vector) and the other will be a 3D object and best represented by a series of points or area.

Which is represented by a cuboid?  A cuboid is neither a ray nor a plane.
Do you mean a plane coincident with one of the faces of the cuboid?

a missile which will have small height if any and say a 3D object like a house.
