⚱️ 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.
