Similar to squares, can you find the number of cubes with 1 digit, 2 digits and 3 digits? What do you observe?

  • 2

Cubes with:
1 digit → 1 to 7³ = 343 (i.e. 1, 8)
2 digits → 4³ = 64 to 9³ = 729
3 digits → up to 9³ = 729
We observe fewer cube numbers compared to square numbers in each range.

  1. Cubes with:
    • 1 digit → 1³ = 1, 2³ = 8
    • 2 digits → 3³ = 27 to 4³ = 64
    • 3 digits → 5³ = 125 to 9³ = 729
    Only a few cubes lie in each range. There are fewer cube numbers than squares in low ranges. For example, there are only 2 cubes below 10 and only 4 or 5 in two-digit range.
