216 cm
786 cm
729 cm
None of the above​

Answer 1

Answer:

surface area of the cube = 6 a sq

one side. =

6 a sq.= 486

a sq. = 486/6

a sq. = 81

a sq. = 9 cm.

Volume of the cube = 9×9×9= 729 cm

Answer 2

Answer:

Surface area of cube = 486 cm^2

6a^2 = 486 cm^2

a^2 = 486/6

a^2 = 81

a = √81

a = 9 cm

Volume of cube = a^3

= 9^3

= 729 cm^3
