sofa cube is 512 cm°. Its total surface area is
​

Answer 1

total surface area of cube equal to 256 CM square

Answer 2

SoluTion :-

$\sf {\underline{\underline{Volume\ of\ cube=512\ cm^3}}}}$

$\because \boxed {V = a^3}$

$\sf {\therefore\ a^3 = 512}\\\\\sf {\implies a = \sqrt[3]{512}}\\\\\sf {\implies a = 8\ cm}$

So,

Surface area of cube = 6a²

= 6 x 8²

= 6 x 64 = 384
