Tutoriais - Programação Orientada a ObjetosDesenvolva uma classe chamada Icosahedron para representar um icosaedro, ou seja, um poliedro regular de vinte faces, considerado um dos cinco Sólidos Platônicos. A classe possui um único atributo denominado edge, do tipo double, que representa a aresta do icosaedro. O construtor da classe recebe como parâmetro a aresta do icosaedro, cujo valor deve ser maior ou igual a zero. A aresta do icosaedro pode ser obtida pelo usuário por meio do método getEdge(). A classe também apresenta os métodos area() e volume(), que retornam a área e o volume do icosaedro, respectivamente. A área de um icosaedro de aresta a é obtida pela fórmula 5 * √3 * a2. O volume de um icosaedro de aresta a é obtido pela fórmula 5 / 12 * (3 + √5) * a3.
