  1. Question 1

    Q1. A cuboidal, block of 6 cm X 9 cm X 12 cm is cut up into an exact number of equal cubes. The least possible number of cubes will be_________?

    • A) 6
    • B) 9
    • C) 24
    • D) 30

    Answer: 24

    Explanation: HCF(6, 9, 12) = 3 cm, so each cube has side 3 cm; number of cubes = (6×9×12)/(3³) = 648/27 = 24.
