    Study Notes

    Geometry Notes

    Surface Area

    • The surface area of a 3D shape is the total area of all its surfaces.
    • Formula: SA = 2(lw + lh + wh) for a cuboid, where l is length, w is width, and h is height.
    • SA = 4πr^2 for a sphere, where r is the radius.
    • SA = 2πr(h + r) for a cylinder, where r is the radius and h is the height.

    Volume of Cuboids

    • The volume of a cuboid is the amount of space inside the cuboid.
    • Formula: V = lwh, where l is length, w is width, and h is height.
    • Unit of measurement: cubic units (e.g. cubic meters, cubic centimeters)

    Oberflächeninhalt (Surface Area in German)

    • Oberflächeninhalt is the German term for surface area.
    • It is the sum of the areas of all surfaces of a 3D shape.
    • Important for calculating the surface area of various shapes, such as cubes, cuboids, and spheres.

    Formeln fuer Volumen (Formulas for Volume in German)

    • Formulas for calculating the volume of different shapes:
      • Cuboid: V = lwh
      • Cube: V = s^3, where s is the side length
      • Cylinder: V = πr^2h, where r is the radius and h is the height
      • Sphere: V = (4/3)πr^3, where r is the radius
      • Cone: V = (1/3)πr^2h, where r is the radius and h is the height
