The entire outer layer is painted so an 8x8x8 block inside isn't painted. Zero. All cubes are painted on at least one side and the 10x10x10 cube is painted on all sides. It's a 10x10x10 cube meaning there are 1000 cubelets. Ones on the inside too. So 8x8x8 = 512.
27 cubes 3x3x3
How many smaller cubes are not painted at all if a cube is painted green on all sides & cut into 64 cubes of equal size?

cubes without paint: 83 = 512. cubes with paint: 103 - 83 = 1,000 - 512 = 488. there's another explanation on this site
Assuming that the cubes are 1x1x1, there will be one thousand cubes in the larger cube.
3x3x3 cube has 27 cubes. One is in the middle and cannot be seen so the answer is 26.

0 sides are not painted! So all the cubes have three faces painted!

There are no cubes in a yard. There are 3x3x3=27 cubic feet in a cubic yard.
No Eastsheen do not make 3x3x3 cubes. I repeat, Eastsheen do not make a 3x3x3!! However, they do make excellent 2x2x2, 4x4x4 and 5x5x5s. There are Eastsheen packs available that contain 4 cubes including a 3x3x3, but if you read the item description closely it is either a Famwealthcube (which are horrinble), a Rubik's brand cube or an unspecified "DIY." You only have to visit their site to confirm that they do not make this item.One point of clarification- there is a new mini 3x3x3 keychain that claims to be Eastsheen. I can't confirm this as it is not on Eastsheen's official site.
