Introduction to Combination of Solids

Understanding How Basic Solids Combine to Form Complex Objects

Welcome! Discover how basic solids combine to form everyday objects around us.
📦 Basic Solids
4 Fundamental Shapes
Cuboid • Cylinder • Cone • Sphere

These are the building blocks of complex 3D objects in our world.

🔗 Combinations
Complex = Basic + Basic

• Oil tanker = Cylinder + Hemispheres
• Test tube = Cylinder + Hemisphere
• Buildings = Multiple solids combined

🎯 Key Strategy
Break → Calculate → Combine

To find surface area or volume:
1. Break into basic solids
2. Calculate each separately
3. Add or subtract as needed

💡 Applications
Engineering & Design

Used in architecture, manufacturing, packaging design, and construction planning.
