Answer:

Volume of a cube= 1/8 cubic meter

We know that volume of a cube= side x side x side

$(side)^{3}$ = $\frac{1}{8}$

From here, we get side of cube= $\frac{1}{2}$ meter

Hence, the side of a cube = $\frac{1}{2}$ meter

We have to find a fraction, when it is multiplied by itself

$\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{4}$

Here we get our answer $\frac{1}{4}$
