Question

What is the answer of this question?? With process​

Answer 1

Answer:

surface area of cube=486 cm

now ,

let a be one of the side of the cube

then,

6a^2=486

a=9 [just solve ]

then volume = 9^3=729cm^3

Answer 2

Answer:

surface area of cube = 6a^2

therefore,

6a^2 = 486

a^2 = 486÷6

a = √81

a = 9cm

Now,

Volume of cube = a^3

= 9^3

= 729 cm3
