You can find the surface area of a cube using the equation [tex]SA=6a^2
[/tex], where a is the length of an edge.
First, substitute. [tex]200200=6a^2[/tex]
Then we simplify. We need to get rid of the squared. The opposite of squaring is square root. [tex] \sqrt{200200} =\sqrt{6a^2 }
\\ 447.437146424=6a[/tex]
Now we isolate the variable by dividing by 6. [tex] \frac{447.437146424}{6} = \frac{6a}{6} \\ 74.5728577373=a[/tex]
The edge length of the cube is about 75.57.
