Question

Um prisma hexagonal regular possui altura igual a 15 cm e perímetro da base 24 cm :

A) A areá da Base C) A areá lateral
B)A areá total D) O volume

Answer 1

Ab = l² √3/4
Ab = 6l²√3/4
Ab = 3. 4²√³/2
Ab = 48√3/2 = 24√3 cm²
Al = 6(l . h)
Al = 6x4x15
Al = 360 cm²
At = 2.Ab + Al
At = 2 . 24√3 + 360
At = 48√3 + 360 cm²
V = Ab . h
V = 24√3.15
V = 360√3 cm³
