Cube numbers, step by step
A cube number is what you get by multiplying a number by itself three times.
The question
12³
12³
12³=12 × 12 × 12
12³=12 × 12 × 12
12 × 12 × 12=1728
- The small number is a COUNT, not something to multiply by. 12³ does not mean 12 × 3 — it means how many 12s to multiply together.
- So write it out: 3 12s multiplied together — 12 × 12 × 12.
- Now it is just multiplying: 12 × 12 × 12 = 1728.
