**Basic Formula of 3D Figures**

Understanding the basic formulas for 3D figures is essential for geometry in the SSC exams. Here are key formulas for common 3D shapes:

1. **Cube**
- Volume: \( V = a^3 \)
- Surface Area: \( SA = 6a^2 \)

2. **Cuboid**
- Volume: \( V = l \times b \times h \)
- Surface Area: \( SA = 2(lb + bh + hl) \)

3. **Cylinder**
- Volume: \( V = \pi r^2 h \)
- Surface Area: \( SA = 2\pi r(h + r) \)

4. **Cone**
- Volume: \( V = \frac{1}{3} \pi r^2 h \)
- Surface Area: \( SA = \pi r(r + l) \) (where \( l \) is the slant height)

5. **Sphere**
- Volume: \( V = \frac{4}{3} \pi r^3 \)
- Surface Area: \( SA = 4\pi r^2 \)

6. **Hemisphere**
- Volume: \( V = \frac{2}{3} \pi r^3 \)
- Surface Area: \( SA = 3\pi r^2 \)

Familiarizing yourself with these formulas will aid in solving problems efficiently in the SSC CGL Mains 2024 exam.
