    ### 🔠 Letter: S / स — *Square and Cube Roots / वर्गमूल और घनमूल*

    #### 📚 Concept:
    - EN: Square and Cube Roots  
    - HI: वर्गमूल और घनमूल

    #### 🧠 Type:
    - EN: Square and Cube Roots  
    - HI: वर्गमूल और घनमूल

    #### 📖 Description:
    - EN: Calculating and reasoning with square roots and cube roots practically.  
    - HI: वर्गमूल और घनमूल की गणना और व्यावहारिक समस्या समाधान।

    #### 📌 Explanation:
    - EN: Square root is inverse of squaring, cube root inverse of cubing. Roots simplify dimensional and volume calculations.  
    - HI: वर्गमूल वर्ग करने का व्युत्क्रम है, घनमूल घन करने का। ये आयाम और आयतन गणना सरल बनाते हैं।

    #### ➗ Formula or Relation:
    - EN: **√a × √a = a, (³√a)^3 = a**  
    - HI: **√a × √a = a, (³√a)^3 = a**

    #### 💡 Example Questions:
    **ENGLISH:**
    ['If the length of a square field is √144 meters, calculate the area of the field using square roots. How would this help in budgeting for fencing the area?', 'A cube’s volume is 729 cubic meters. Find the length of each side using cube roots. Subsequently, calculate the total surface area of the cube.', 'During a competitive exam, a question asks to find the square root of 0.0081 and cube root of 0.027. Provide stepwise calculations and verify the answers.']

    **HINDI:**
    ['एक वर्ग खेत की लंबाई √144 मीटर है। खेत का क्षेत्रफल वर्गमूल की सहायता से निकालें। इससे खेत की बाड़ लगाने के बजट पर क्या प्रभाव पड़ेगा? समझाएँ।', 'एक घन की मात्रा 729 घन मीटर है। प्रत्येक भुजा की लंबाई घनमूल की मदद से निकालें। फिर घन की कुल सतह क्षेत्रफल ज्ञात करें।', 'प्रतियोगी परीक्षा में पूछा गया प्रश्न: 0.0081 का वर्गमूल और 0.027 का घनमूल निकालें। चरणबद्ध समाधान दिखाएँ और उत्तर सत्यापित करें।']
