Pyramid Frustum Volume Calculator
This calculator computes the pyramid frustum volume: exact formula V = ⅓h(A₁+A₂+√(A₁A₂)), worked example bases 6 & 4 cm, h = 5 → 126.67 cm³.

How the pyramid frustum volume Calculator Works
The calculator applies the exact formula V = ⅓·h·(A₁ + A₂ + √(A₁·A₂)). Worked example: square bases 6 cm and 4 cm, h = 5 cm → V = 126.67 cm³. Keep every input in one unit system and the result follows in cubic units (m³, ft³, liters); full precision is kept until the final rounding. Radius fields expect radii — halve any diameter before entering it.

Tips
- 1
Volume scales with the cube of linear dimensions
- 2
Convert results: 1 m³ = 1000 L, 1 ft³ = 7.48 US gal
- 3
π ≈ 3.14159 — precision kept to the last step
Common Mistakes
Mixing units (cm radius with m height)
Entering a diameter where the formula wants a radius
Forgetting the solid must be closed — check h > 0
