In Huckleberry Finn, a classic American novel by Mark Twain, much of the story takes place on a raft on the Mississippi river. Huckleberry's raft is a square 5 meters on a side with a vertical height of 0.1 m. If Huckleberry isn't on the raft it floats such that the top of the raft remains 0.07 m above the surface of the water. Huckleberry and his friend Jim, with a combined mass of 130 kg, climb on the raft. How far above the surface of the water **in meters** is the top of the raft after Huckleberry and Jim climb on?

Oh, and the Mississippi river is primarily fresh water...

**Details and assumptions**

- Treat the raft as just a rectangular prism/cuboid. You can ignore for the purposes of the problem that it's made of logs.
