Serpentinite is typically formed from the alteration of ultramafic rocks (like peridotite) through hydration and metamorphism. These ultramafic rocks are usually found deep within the Earth's crust and are considered intrusive rocks. So, serpentinite is formed from an intrusive rock and is not considered either extrusive or intrusive itself.
Sandstone is not extrusive. However, it is intrusive. It is intrusive because it cools before it reaches the actual surface.
