Regular Bifrustum Calculator
Calculations in a right regular bifrustum. This is a regular frustum with an identical frustum attached to its base. Enter both side lengths a and b, a height h or H and the number of vertices of the bases. Choose the number of decimal places, then click Calculate. The half height h is the height of the original frustum.

Formulas:
H = 2 * h
L = 1/2 * n * ( a + b ) * √ cot²( π/n ) * ( a - b )² + 4h²
A = L + n * b² / ( 2 * tan(π/n) )
V = n * h * ( a² - b² ) / ( 6 * tan(π/n) )

Lengths and heights have the same unit (e.g. meter), the area has this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter). A/V has this unit ^{-1} .
