3D Shapes Problem Solving

Larry presents a bonus problem on calculating the surface area of 3D shapes using a grid of cubes. He explains the problem, discusses an initial approach, and provides a detailed solution with visualization. Larry then implements the solution in code, tests it, and addresses any issues through debugging. He concludes with final thoughts on the problem's complexity and its suitability for competitive programming.
