Question 298199
how can i work out the length, height and width of a cube when i only have the volume (48cm3)? i have used the calculator's cube root function. But is there a more practical working out.

Since it's a cube, the length, height, and width are all the same,
and we just speak of an "edge" and call it "e".

{{{V = e^3}}}
{{{48 = e^3}}}
Take cube roots of both sides:
{{{root(3,48)=root(3,e^3)}}}
{{{root(3,8*6)=e}}}
{{{root(3,8)*root(3,6)=e}}}
{{{2*root(3,6)=e}}}

So each edge of the cube is {{{2*root(3,6)}}}.
And the edge is the same as the length, height, and width.
