A boat carrying a large number of stones is floating in a water tank. What will happen to water level if the stone are unloaded into water?

Explanation

To solve the problem of what happens to the water level when stones are unloaded from a boat into a water tank, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Initial Situation**: The boat is floating in the water tank with a large number of stones. The boat displaces a certain volume of water equal to the weight of the boat plus the stones.

2. **Principle of Buoyancy**: According to Archimedes' principle, the weight of the water displaced by the boat is equal to the total weight of the boat and the stones it carries. This means that the boat is floating because it displaces a volume of water that weighs the same as the total weight of the boat and stones.
