Me ajuda por favor, responda todas as questões obrigada

Answer 1

Resposta:

1- tetraedro possui 4 faces retangulares, 4 vértices e 6 arestas.

prisma de base octogonal V = 16 e F = 10. A = 24

Prisma Hexazonal 10 vértices 10 face e 18 arestas

2-Um prisma de base octogonal tem 16 vértices, 24 arestas e 10 faces.

3-(I)

Vértices = 6  ( piramide de 6 vertices PENTAGONAL)

faces = 6

arestas = 10

(II)

faces = 10  (piramide ENEAGONAL)

vertices = 10

arestas = 18

(III)

vertices =8 ( piramide HEPTAGONAL)

faces = 8

arestas =14

(IV)

faces = 4  ( piramide  TRIANGULAR)

Vertices = 4

arestas  =  6
