As afirmações fornecidas referem-se a conceitos de cálculo multivariável, particularmente no que diz respeito a integrais duplas e suas aplicações. Vamos avaliar cada afirmação: I. Para calcular uma integral dupla em uma região retangular, não usamos dodecaedros. Integrais duplas são usadas para calcular volumes sob superfícies e são aproximadas pela soma dos volumes de prismas retangulares (ou às vezes cilindros em coordenadas polares) no processo limite, não de dodecaedros. Esta afirmação está incorreta. II. O vetor gradiente é um vetor de derivadas parciais que aponta na direção da maior taxa de aumento de uma função. Não é usado diretamente para calcular integrais iteradas. Integrais iteradas são geralmente calculadas usando antiderivadas em relação a uma variável de cada vez. Esta afirmação está incorreta. III. O volume da superfície, mais precisamente referido como o volume sob uma superfície, é de fato aproximado pelo limite da soma de Riemann para funções de duas variáveis. No contexto das integrais duplas, à medida que o número de subdivisões se aproxima do infinito, a soma de Riemann se aproxima do volume exato sob a superfície de uma determinada região. Esta afirmação está correta. Com base nas informações fornecidas, apenas a Afirmação III está correta. As afirmações I e II estão incorretas.
