Question

a cube has a volume 343m3.find the length and total surface area

Answer 1

answer of this question is 294

Answer 2

we know,
$volume \: of \: a \: cube = {s}^{3}$
$343 = {s}^{3}$
$side = \sqrt[3]{343}$
each side of cube=7m

$total \: surface \: \: area \: of \: a \: cube \\ = 6 {l}^{2}$
$= 6( {7})^{2}$
$= 294 {m}^{2}$
is the answer.
