Question

Um cubo possui todas as arestas medindo 4 cm . Calcule :

a) area da base
b)area lateral
c)area total
d) diagonal
e)volume

Answer 1

a = 4 cm

a) L² = 4.4 = 16 cm²

b) 4 . AF ( área da base )

4 . 4² = 4.16 = 64 cm²

c) At = 6a²

At = 6.4²

At = 6.16

At = 96 cm²

d) D = a√3

D = 4√3 cm

e) V = a^3

V = 4^3

V = 64 cm^3
