    Study Notes

    Definition and Importance

    • Mensuration is the process of measuring the perimeter, area, and volume of various geometric shapes and objects.
    • It is an essential concept in mathematics, physics, engineering, and other fields where calculations of size and quantity are crucial.

    Perimeter

    • The perimeter of a shape is the distance around it.
    • Formula: Perimeter = 2(Length + Width) for a rectangle
    • Formula: Perimeter = π × Diameter for a circle

    Area

    • The area of a shape is the amount of space inside it.
    • Formula: Area = Length × Width for a rectangle
    • Formula: Area = π × Radius^2 for a circle
    • Formula: Area = (Base × Height) / 2 for a triangle

    Volume

    • The volume of an object is the amount of space inside it.
    • Formula: Volume = Length × Width × Height for a rectangular prism
    • Formula: Volume = (4/3) × π × Radius^3 for a sphere
    • Formula: Volume = (1/3) × Base × Height for a pyramid

    Surface Area

    • The surface area of an object is the total area of all its surfaces.
    • Formula: Surface Area = 2 × (Length × Width + Length × Height + Width × Height) for a rectangular prism
    • Formula: Surface Area = 4 × π × Radius^2 for a sphere

    Real-World Applications

    • Architecture: calculating the area and volume of buildings
    • Engineering: designing and building bridges, roads, and other structures
    • Physics: calculating the volume and surface area of objects in motion
    • Everyday life: measuring rooms, furniture, and other objects
