per base il quadrato sapendo che l'altezza del prisma è \( \frac{4}{3} \) del lato del quadrato. Un prisma retto ha per base un triangolo isoscele con la base che misura 16 dm e l'area di \( 120 \mathrm{dm}^{2} \). Sapendo che l'altezza del prisma è lunga 9 dm , calcola l'area della superficie totale.
