The 20 cm cube can be sliced into four(a) layers - each one 20 cm wide, 20 cm long and 5cm high.
Each of those layers can be sliced into four(b) strips 20 cm wide, 5 cm long and 5 cm high
Each of those strips can be sliced into four(c) cubes 5cm wide, 5 cm long and 5 cm high
Four(a) x four(b) x four(c) = 64

A cube of 3x3x3 is painted from all the 6 faces If you cut the cube in 27 equal cubes of 1x1x1 then how many cubes will be painted from exactly 2 faces?

A cube is painted green on all the sides. it is then cut into 64 cubes of equal size. how many of smaller cubes are painted on 1 side?
Cube root of 64 is 4 therefore cube is 4 x 4 x 4. Each side of the cube has 16 visible small cube faces, 4 of which are corners (3 green sides) and 8 more are edges (2 green sides), so there are only four small cubes with one green face on each of the six sides of the large cube. Your answer is therefore 24.
