Now, remember what makes that cube green, and look back at the red cube. Bring to the forefront of your mind the reason why that cube is red, and replace that with what makes the other cube green. This will not make the cube green, but it is the first step, and it may take a few tries for you, Kelly, since you haven't done Realmatic transformations before.
