MENSURATION (Part 2)
Mensuration is the branch of mathematics that deals with measuring geometric shapes. It helps calculate things like area, volume, surface area, and perimeter. The main concepts are:
- Perimeter: The total distance around a 2D shape (e.g., for a rectangle, it’s the sum of all its sides).
- Area: The space inside a 2D shape (e.g., for a triangle, it’s 1/2 × base × height).
- Volume: The amount of space a 3D object occupies (e.g., for a cube, it’s side³).
- Surface Area: The area of all surfaces of a 3D object (e.g., for a sphere, it’s 4πr²).
