Problem 1: Cube - a cube of 12 cm is cut into small 3cm pieces.. then place another 4 small cubes over it.. and another 2 small cubes over the 4 cubes.. then again one more cube over the 2 cubes.. the cube is then painted from top to bottom.

this is the problem which is given at cognizant placement drive. please solve this for me and this group members who can attend that drive.
most of the problems like this in CTS.
Clue for problem
(12/3=4... so 4 row 4 column.. draw a dig of cube first. Imagining the cube only help you to solve rather than formulas.) Problem 2: ANALTICAL SECTION
