The document you provided appears to be a group project focused on applying mathematical concepts to physical models, specifically involving limits, density, and buoyancy. Here are the key aspects of the assignment:

1. **Learning Objectives**:
   - Apply mathematical concepts to model physical processes.
   - Find limits of functions and explain them in a physical context.
   - Work with algebraic expressions that include parameters (e.g., radius \( r \), length \( \ell \), and density \( \rho \)).
   - Communicate mathematical content clearly.

2. **Assignment Setup**:
   The task revolves around hollow capsules, analyzing their ability to float or sink based on their density and shape.

3. **Mathematical Challenges**:
   - Finding a formula for the capsule's density as a function of its radius and length, considering mass per unit area.
   - Investigating the behavior of the capsules when the radius increases indefinitely.
   - Comparing capsules of different shapes (cube, cone, pyramid, dodecahedron) to predict their buoyancy behavior.

Would you like me to help solve a particular question from the document? Here are 5 related questions to think about:

1. What is the formula for the density of a cylindrical capsule?
2. How does a capsule behave (float or sink) as the radius becomes very large?
3. How would you apply limits to the buoyancy of non-spherical shapes like cubes or cones?
4. What factors affect whether a very small capsule floats or sinks?
5. How does surface area affect the buoyancy of large versus small capsules?

**Tip**: When solving for limits, always visualize what happens as a parameter approaches infinity or zero, as this gives insight into the physical system's behavior.

In this project, you will use limits to imagine what would happen in a system if a particular object were very large or very small. You will also practice using parameters (unknown constants, like r and ℓ) in algebraic expressions. We are concerned with whether each capsule will float or sink when placed in a fluid, based on density and shape. You need to find formulas, evaluate limits, and predict buoyancy behavior for different shapes (cube, cone, pyramid, dodecahedron).

Explore how to use limits and algebraic expressions with parameters like radius and length to model buoyancy behavior of capsules in various shapes. Understand key concepts of density, buoyancy, and limits to predict whether objects float or sink in a fluid. Suitable for university-level students studying mathematical models of physical processes.
