Question

determine a área total e o volume do prisma hexagonal regular reto

(exercício de prisma)

Answer 1

$A= \frac{6^{2}\sqrt{3}}{4}\\A= \frac{36\sqrt{3} }{4}\\A= 9\sqrt{3} \\\\\sqrt{3}= aproximadamente  1,73\\A= 9.1,73\\A= 15,57 dm^{2}  \\\\V= 9\sqrt{3} . 15\\ V= 135\sqrt{3}\\ V= 135. 1,73\\V= 233,55 dm^{3}$
