There are eight cubes. One of them is heavier than the others, and we need to find it (They are all identical). How can we tell, using a balance, which cube is the heavy one in two weighings.

Divide them into three groups: two groups of three and one group of two. Now weigh the two groups of three against each other. If one is heavier, you narrowed it down to three. If they are equal you narrowed it down to two.
Can you see how you can now complete the task, with just one more weighing?
