Tutoriais - Programação Orientada a ObjetosDesenvolva uma classe chamada Tetrahedron para representar um tetraedro, ou seja, um poliedro regular de quatro faces, considerado um dos cinco Sólidos Platônicos. A classe possui um único atributo denominado edge, do tipo double, que representa a aresta do tetraedro. O construtor da classe recebe como parâmetro a aresta do tetraedro, cujo valor deve ser maior ou igual a zero. A aresta do tetraedro 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 tetraedro, respectivamente. A área de um tetraedro de aresta a é obtida pela fórmula √3 * a2. O volume de um tetraedro de aresta a é obtido pela fórmula √2 / 12 * a3.
