What is the minimum number of cuts required to divide a cuboid into 12 equal cuboids?
Show answer & explanation
Correct answer: B
Explanation
The cuboid is to be divided into 12 equal parts.
Minimum cuts for n parts = (x−1) + (y−1) + (z−1)
Where x × y × z = 12 ⇒ 3 × 2 × 2
Cuts = (3−1) + (2−1) + (2−1) = 2 + 1 + 1 = 4 cuts
