A large cube is built from centimeters cubes. The faces of the large cube are painted .Of the centimeter cubes, 1000 are unpainted how many of the centimeters cubes are painted on one face
The inner ones are not painted.
So (L-1) cubed=1000 solve for L.
Then, the number painted on one face is 6*(L-1)^2 . Check my thinking
U R CORRECT.........
