Compound Joint Angle Calculator for N-Sided Box

Tapered N-Sided Box Calculator

Tapered N-Sided Box Calculator

Calculates cutting angles and dimensions for pyramidal frusta (tapered boxes)

Frustum Definition: In geometry, a frustum (plural: frusta or frustums) is the portion of a solid (normally a pyramid or cone) that lies between two parallel planes cutting it. A right pyramidal frustum is a frustum created by slicing the top off a pyramid with a cut parallel to the base.

Examples: Common frusta include lampshades, buckets, and tapered containers. This calculator handles right pyramidal frusta with 3 to 24 sides.

(90° = straight sides, smaller angles = more taper)

Cutting Angles:

Miter Angle: 30.0°
Bevel Angle: 7.6°

Frustum Dimensions:

Circumference At Top: 24.00in
Diameter At Top: 7.64in
