Cube of 10
10 cubed equals 1000. Cubes show up in volume calculations — a cube with side 10 holds 1000 cubic units.
Cubes carry the fingerprint of their base. The final digit of 1000 is 0 — always the cube of the base's own final digit. Divided by 9, a cube only ever leaves 0, 1 or 8, and 1000 leaves 1. The volume picture explains the name: a 10 × 10 floor of unit cubes holds 100 of them, and 10 such layers stack to 1000 — the shape itself is the exponent at work. The gaps grow like a parabola: 1000 − 729 = 271, which is 3 × 10 × 9 + 1 — each new layer wider than the last. Even base, even cube: 1000 keeps the parity of 10.
