Question

find the volume of the cube whose surface area is 486cm square.(get 70 points)​

Answer 1

Surface area of cube = 6 edge^2486

486= 6edge^2

486/6 = edge^2

81 = edge^2

√81 = √edge^2

9 cm = edge

Volume = edge^3

= 9^3

= 9 x 9 x 9

= 729 cm cube

hope you understand...........................................

Answer 2

Answer:

729 cm³

Step-by-step explanation:

Surface area of cube = 6S²

∴ 6S² = 486 cm²

∴ S² = 81

∴ S = 9 cm

Volume = S³

Volume = 9³ = 729 cm³
