Answer 1

Answer:

THE SURFACE AREA OF CUBE IS 486cm²

Step-by-step explanation:

VOLUME OF CUBE = 729cm³

SO,

SIDE OF THE CUBE = ∛729cm³

                                  = 9cm

SO,

WE KNOW,

SURFACE AREA = 6*a²

                            = 6*(9cm)²

                            = 6*81cm²

                            = 486cm²
