soldier1979 [14.2K]

Answer:

$x=2\sqrt{\frac{14}{3}}\ units$ or $x=\frac{2}{3}\sqrt{42}\ units$

Step-by-step explanation:

we know that

The surface area of a cube is equal to

$SA=6x^{2}$

where

x is the length side of a cube

In this problem we have

$SA=112\ cm^{2}$

substitute in the formula and solve for x

$112=6x^{2}$

$x^{2}=112/6$

square root both sides

$x=\sqrt{\frac{112}{6}}\ units=2\sqrt{\frac{14}{3}}\ units=\frac{2}{3}\sqrt{42}\ units$
