thesmartone · Answer

$\sf Surface~Area = 6s^2$
$\sf 160 = 6s^2$

thesmartone · Answer

What is $\sf\Large\frac{160}{6}=?$

anonymous · Answer

rounded to the nearest tenth @TheSmartOne?

thesmartone · Answer

Well we want the most exact answer at the end so we can round to at least 3 digits and then for the final answer round to the tenth.

anonymous · Answer

So $$\frac{ 160 }{ 6 } = 26.6$$

Would that be right @TheSmartOne?

thesmartone · Answer

Yes.

And so now we have
$\sf 26.6 = s^2$
Now we have to take the squareroot of 26.6
And then we will get
$\sf\large\sqrt{26.6}=s$
