Question

512 Smaller But Identical Cubes Have Been Put Together To Form A Larger Cube. This Larger Cube Is Now Painted On All 6 Faces. How Many Of The Smaller Cubes Have At Most Two Faces Painted?

Answer 1

Answer: Divided into 512 equally big cubes, right? OK. So 8 x 8 x 8. That means we have 8 x 8 = 64 mini cube-sides painted on each face of the original cube that has 6 faces. So, 6 x 64 = 384 painted sides.

Now the the 384 sides is formed into a single cube of 6 sides.

384/6= 64

∴64 cubes
