ANSWER
Since all sides of the cube are painted, and the two figures do not show any overlapping colour, so you have to mentally align the two cubes shown to obtain the complete cube.
But here we could employ an intelligent short cut. Since both are pictures of the same cube showing no overlapping colours implies that they have been taken from diagonally opposite vertices. Hence every pair of corresponding colours are actually oppositely placed. This means that white is opposite to orange. And green is opposite to yellow and finally blue is opposite to red.
Think over my explanation. Once you understand it, then explain it in your own words. This is very crucial since it will be registered in your brain once you do so.
