Fact #1: A cube has six faces. Fact #2: Every one of them has the same area. Fact #3: The surface area of each face is (the length of the cube's side)² Now that I look at this one more carefully, the only thing you need to know to solve it is Fact #3.  (But you can keep the others and save them for later.) The surface area of each face is (the length of the cube's side)² 64 is the (length of the cube's side)² Can you find a number that gives you 64 when you multiply it by itself ? That's the length of the cube's side. Hint: If you don't get ' 8 ', work on it a little more.
