Question

Do I need more than 6, 000 pieces of Legos to build the Death Star

Short answer: It depends on the size and how detailed you want it. For small desktop models you can stay well under 6,000 pieces; for a mid-to-large display sphere you may need more.

Quick benchmarks (approximate):
- Ornament / small desk model (4–6" / 10–15 cm): a few hundred to ~1,000 pieces.
- Medium desk model (8–12" / 20–30 cm): roughly 1,500–6,000 pieces (depending on building technique).
- Large display sphere (≈16" / 40 cm): likely several thousand up to >8,000 pieces if you use many small tiles/1x1s.
- Full-scale, highly detailed Death Star with interior rooms: tens of thousands of pieces.

A simple way to estimate:
- Convert the target diameter to LEGO studs (1 stud ≈ 8 mm).
- Surface area of a sphere ≈ 4πr^2 (in studs^2 if r is in studs).
- If you cover the surface with 1×1 tiles, the number of tiles ≈ surface area. Using larger plates/bricks reduces piece count a lot.

Example: a 16" (≈406 mm) sphere is about 51 studs across. Surface area ≈ 4π*(25.5^2) ≈ 8,000 studs, so using 1×1 tiles would need ≈8,000 pieces; using plates/techniques will reduce that.

If you tell me the diameter (or show an image/target set) and whether you want interior detail, I can give a tighter estimate and a parts-count range.
