Integración Numerica 3D en VBA

Buenas tardes,

Alguien tiene o sabe dónde encontrar un código en VBA que permita resolver integrales numéricas volumétricas (3D) en coordenadas cartesianas?

Se que existen métodos tipo la regla se Simpson o los teoremas de Newton-Cotes que permiten integrar funciones unidiminesionales, pero no conozco ni he encontrado formulaciones para integración de funciones de tres dimensiones (integral triple(x, dx·dy·dz) en intervalos definidos)

Me interesa solucionar este tema para encontrar el centro de gravedad de una cuña cilíndrica en función de las dimensiones de ésta.

Muchas gracias por la respuesta!

Te comparto un libro de excel para integrales por medio de código VBA
