Question: Surface Area Formulas
CUBE
Formula: SA = 6s²
RECTANGULAR PRISM
Formula: SA = 2lw + 2lh + 2wh
SQUARE PYRAMID
Formula: SA = s² + 2sl
CYLINDER
Formula: SA = 2πr² + 2πrh
CONE
Formula: SA = πr² + πrl
SPHERE
Formula: SA = 4πr²
COMPOSITE SOLIDS
Formula: Sum of exposed surface areas only.
GIVE ME THREE REAL LIFE EXAMPLES FOR EACH OF THE OBJECTS
1. **Problem Statement:**
List three real-life examples for each solid shape: cube, rectangular prism, square pyramid, cylinder, cone, sphere, and composite solids.
2. **Cube (SA = 6s^2):**
- Dice used in board games.
- Rubik's Cube puzzle.
- Ice cubes.
3. **Rectangular Prism (SA = 2lw + 2lh + 2wh):**
- A shoebox.
- A brick.
- A cereal box.
4. **Square Pyramid (SA = s^2 + 2sl):**
- The Great Pyramid of Giza.
- Tent with a square base.
- A pyramid-shaped paperweight.
5. **Cylinder (SA = 2\pi r^2 + 2\pi rh):**
- A soda can.
- A candle.
- A soup can.
6. **Cone (SA = \pi r^2 + \pi rl):**
- An ice cream cone.
- A party hat.
- Traffic cone.
7. **Sphere (SA = 4\pi r^2):**
- A basketball.
- A globe.
- A soap bubble.
8. **Composite Solids:**
- A house with a rectangular base and a triangular roof.
- A cylinder with a hemisphere on top (like a water tank).
- A cone on top of a cylinder (like an ice cream cone with a cup).
Each example corresponds to the shape's surface area formula and real-world objects that approximate these shapes.
