Programação Orientada a Objetos

Desenvolva uma classe chamada TruncatedCuboctahedron para representar um cuboctaedro truncado, ou seja, um poliedro semi-regular composto por doze quadrados, oito hexágonos e seis octógonos, considerado um dos treze Sólidos de Arquimedes. A classe possui um único atributo denominado edge, do tipo double, que representa a aresta do cuboctaedro truncado e cujo valor deve ser maior ou igual a zero e menor ou igual a quarenta. A aresta do cuboctaedro truncado pode ser obtida e alterada pelo usuário por meio dos métodos getEdge() e setEdge(), respectivamente. A classe também apresenta os métodos area() e volume(), que retornam a área e o volume do cuboctaedro truncado, respectivamente. A área de um cuboctaedro truncado de aresta a é obtida pela fórmula 12 * (2 + √2 + √3) * a2. O volume de um cuboctaedro truncado de aresta a é obtido pela fórmula (22 + 14 * √2) * a3.
