### **STUD‑SPACING SHOWDOWN — Day 6 Summer‑Series Mini‑Quest**

Today you’ll flex real‑world reno math. Tape measure in one hand, calculator in the other, and you’re off to the races. The blueprint for a small cabin wall is attached as **wall\_day6.png** (simple elevation sketch—nothing fancy).

Once the **fifth** correct solution lands in **General** , the lumber yard closes and the prize rack is empty. Ready to frame? 🪚📏

#### 👀 **The Job Site**

The drawing shows **one exterior wall** with these specs (all dimensions are already marked‑up on the sketch):

| Item | Detail |
| --- | --- |
| Wall length | **22 ft 0 in** |
| Wall height | **8 ft 0 in** |
| Openings | • **36″ × 48″ window** — centred 6 ft from the left end to its RO centre line |
| • **32″ × 80″ door** — 5 in from the right end to its RO edge | |

Use standard North‑American light‑frame rules throughout:

- Stud spacing: **16″ on‑centre (O.C.)**
- Each opening gets **two king studs** (full height) on each side
- Ignore trimmers—count only king/full‑height studs
- Floor system joists also run **16″ O.C.** (rim joists excluded)
- Two‑ply **2 × 10** headers over every opening

#### 💰 **Prize Pool**

**150 000 $RENOVATION coins** to each of the first **five** correct solvers.

* * *

#### 📌 **Where to Post**

Open **General** → **New Topic** → **Stud‑Spacing Puzzle —**

* * *

#### 📔 **What to Include**

1. **Decoded mantra** (three letters, sorted **alphabetically** , any case)
2. **Your Solana wallet address** (one per member)

* * *

#### 🛠 **Tiny Trail of Breadcrumbs**

1. **A — Stud Count**  
2.Formula\*: `⌊wall_length_in/16⌋ + 1 + (4 king studs × 2 openings)`
2. **B — Joist Count** for a **11 ft 0 in** clear span floor (again 16″ O.C., rims don’t count).
3. **C — Header Plies**  
5.Two‑ply 2 × 10\* over each opening → just total the individual planks you’d buy.

> **Convert** each answer to a letter with the classic **A1Z26** scheme (1 → A … 26 → Z).  
> **Sort the three letters alphabetically** to read a familiar builder’s mantra.

_Need a nudge?_ Remember that `math.floor()` is every framer’s best friend, waste is cheaper than a second yard run, and you can always subtract 26 until your number lives in the alphabet.

#### 🏁 **How to Submit**

```auto
Decoded mantra: "<your three‑letter answer>"
Solana wallet: xxxx...xxxx

```

Smash **Post**. If you’re among the first five right answers, the airdrop is yours. Public TX hash follows for bragging rights.

#### 🤔 **FAQ**

**“Can I brute‑force it?”**  
You could—but a dozen keystrokes on a calculator beats 17,576 guesses.

**“Multiple wallets?”**  
Nope—one Solana address per member. Duplicates or Sybils VOID entries.

**“I’m late—can I still try?”**  
Puzzle stays open until slot five fills _or_ the Summer Series wraps—whichever comes first.

Measure twice, count once, and race for that **150 k bag**. Good luck, renovators! 🛠🧑‍🔧
