Question

$the \: volume \: of \: cube \: is \: \frac{2197}{729} {cm}^{3} .find \: its \: side$

Answer 1

hey mate!!

volume of a cube is (side)^3 , let side be s

so, s^3=2197/729

s=3√2197/729
s=13/9


hope it helps!!

Answer 2

Let the length of a cube be l.

$volume \: of \: cube = {l}^{3}$
$\frac{2197}{729} = {l}^{3} \\ l = \sqrt[3]{ \frac{2197}{729} } \\ l = \frac{13}{9}$
Hence the length is 13/9 cm.
