Real-world examples of cross-sections in everyday objects

📚 Quick Study Guide

• 🔪 Definition: A cross-section is the shape you get when you slice straight through an object.
• 🍎 Visualization: Imagine cutting an apple in half; the exposed surface is the cross-section.
• 📐 Geometric Shapes: Cross-sections can reveal different geometric shapes within a 3D object.
• 🍞 Everyday Examples: Bread, fruits, vegetables, pipes, and even buildings can be used to visualize cross-sections.
• 💡 Applications: Understanding cross-sections is useful in fields like engineering, medicine (CT scans), and architecture.
