Answer:
Step-by-step explanation:
We can start by seeing that cutting the cube up into 64 smaller cubes means cutting it up in a 4×4×4 (since cube has three sides hen we see) grid since the square root of 64 is 4.
So we have two 4×4 yellow faces. But! We need to discard the edges between them, since they have yellow on two sides. Thus, we have two 4×3 faces - and 2× (4×3)=24
Therefore, 24 sides which means 8 cubes have three side painted.
