Question 12
Back to Exercise
A large cube is cut into small cubes of edge 2 cm, with nothing wasted.
How many small cubes are obtained?
- A 1,331 Correct
- B 5,324
- C 121
- D 2,662
Correct Answer: Option A
Edge of large cube = ∛10,648 = 22 cm
Small cubes along each edge = 22 ÷ 2 = 11
Number = 11³ = 1,331
Trap: 5,324 divides the volume by 2, not by 2³.
Answer: 1,331
