Volume of Triangular Frustum

triangular-frustum.png

Dimensions:

Bottom base

A =   , B =   , C =  

Top base

a =   , b = B·aA , c = C·aA

Height - h =  

Bottom base

Semiperimeter

p = 0.5·(A + B + C)

Area (Heron equation)

A1 =  p·(p – A)·(p – B)·(p – C)

Top base

Semiperimeter

p = 0.5·(a + b + c)

Area (Heron equation)

A2 =  p·(p – a)·(p – b)·(p – c)

Volume

V = h3·(A1 +  A1·A2 + A2)

The sum of each two sides must be greater than the third.
