Answer: C= 10
Step-by-step explanation:
Here's the solution,
let the sides of cube be a
now, we know
<em><u>Surface area </u></em>=

So,

Each side of <em><u>cube</u></em> measures 2.5 cm
<em><u>volume</u></em> :
=》

=》

=》

=》

This problem is tough until you clean it up so you can see what's going on.
On the left side, (7 + 5 - 3) = 9 . So the left side is x + 9 .
On the right side, (16 - 8) = 8.
So the equation is really <u>x + 9 = 8</u>
Subtract 9 from each side: <em> x = -1</em>
