Question

volume of a cube is 512 cm°. Its total surface area is
​

Answer 1

Answer:

Volume of cube=512cm^3

a^3=512

a=8 cm

So,

Surface area of cube = 6a^2

=6*8^2

=6*64=384

Answer 2

$\mathbb\red{ \tiny A \scriptsize \: N \small \:S \large \: W \Large \:E \huge \: R}$

Volume of cube = $512 cm^3$

$a^3 = 512$

$a = 8 cm$

Surface area of cube = $6a^2$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: = 6 × 8^2$

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: = 6 × 64 = 384cm^2$
