**Knights**, Thursday, March 21, 2013 at 5:36pm5 sides of the top cube is exposed.

so we get 1*1 * 5 = 5 in ^2

the second cube has 4 sides exposed also, so 2^2 * 4 = 16 in ^2, but also it has one side with the cube on top, so we have 4-1 = 3 on that side, so the overall is 19 in ^2

Then we have for the third cube 5 sides exposed, so we have 3^2 * 5 = 45. We also have the area of the 2in cube on it, so we get 3^2 - 2^2 = 9-4 =5.

So the overall is 45+5+19+5 = 55+19 =74 if i am not mistaken...
