Question

Find the side of a cube whose volume is 343 by 27 metre cube

Answer 1

volume=side³
343\27cm³=a³
(7)³/(3)³ = a³
(7/3)³ =a³
a =7/3

Answer 2

Mensuration,

We have,
A cube whose volume is 343/27 m³

Let one side of the cube as x m

A.T.Q.
${x}^{3} = \frac{343}{27} \\ x = \sqrt[3]{ \frac{343}{27} } \\ x = \sqrt[3]{ \frac{7 \times 7 \times 7}{3 \times 3 \times 3 } } \\ x = \frac{7}{3} m$
So, the sides of the cube is 7/3 m

That's it
