Answer:
x^2+x^2+x^2+x^2+x^2+x^2 cm^2
Step-by-step explanation:
We see 6 blanks in the given line of equations. And since a cube has 6 sides it is only reasonable to think that they want us to put the area of each induvidual side in each of the blanks. That's easy, all you have to do is multiply x by x for each side. So we get, x^2+x^2.... etc.
