Answer 1

Hey buddy ur answer ☝️

Answer 2

$\underline\bold{\huge{ANSWER \: :}}$

Let "a" cm be the length of an edge of a cube.

Then, its volume = a³ cm³

Also, given volume of cube = 512 cm³

So, by condition, we can write :

a³ = 512 cm³

=> a = 8 cm.

Now, total surface area of a cube

= 6 (length of an edge of cube)²

= 6 (8)² cm²

= 384 cm² [ANS.]

SO, THE ANSWER IS $\bold{384 \:\: sq. cm}$
