A cube is to be cut into 8 pieces of equal size and shape. Here, each cut should be straight and it should not stop till it reaches the other end of the cube. The minimum number of such cuts required is
- 3
- 4
- 7
- 8
Correct answer: 3
Solution
Cutting once along each of the three mutually perpendicular axes divides the cube into 2x2x2 = 8 equal pieces. Three cuts suffice, and fewer is impossible, so the minimum is 3.
