⚱️ Understanding Frustum
A frustum is a truncated cone or pyramid. Volume = (1/3)πh(r₁² + r₁r₂ + r₂²).

❓Frequently Asked Questions
What is a frustum and how is it different from a cone?
A frustum is a cone with its top cut off parallel to the base, creating two circular faces:
Cone: One circular base, tapers to a point
Frustum: Two circular bases (different sizes), no pointed apex
Common examples include lamp shades, buckets, and truncated pyramid structures.
How do I remember the frustum volume formula?
The frustum formula can be remembered as a combination of areas:
V=(h/3)[r₁² + r₁r₂ + r₂²]
Think of it as: (height/3) × (sum of: base₁², mixed term, base₂²)
The mixed term r₁r₂ accounts for the transition between the two circular faces.
🎯Common Use Cases
🏗️ Construction & Architecture
- Design truncated columns and architectural supports
- Calculate material for tapered building elements
- Plan frustum-shaped decorative features
- Size truncated pyramid structures
🏭 Industrial & Manufacturing
- Design tapered pressure vessels and tanks
- Calculate volume for conical hoppers and funnels
- Plan truncated cone-shaped containers
- Optimize lamp shade and lighting fixture designs
💡Calculator Tips & Best Practices
📏Special Cases
When r₂ = 0, frustum becomes a cone; when r₁ = r₂, it becomes a cylinder - verify with appropriate formulas.
💡Height Measurement
Height must be measured perpendicular to the bases, not along the slanted side - this is crucial for accurate calculations.
