Answer Posted / chethan d&
firstly,1000 cubes together makes a cube.
Cube=Side*Side*Side
therefore, side is equal to 10 units. (10*10*10=1000)
when the big cube is painted only the outer sides are
painted on thier outer side. therefore if we find out the
area of the each side, we can easily find out unpainted
cubes.
area=side*side (i.e. 10*10=100 units)
a cube has 6 sides, therefore 100*6=600 units.
therefore unpainted cubes are 1000-600=400
the answer is 400!
