    Surface Area and Volume Formulas

    • Cuboid:

      • Lateral/Curved surface area: 2h(l+b)
      • Total surface area: 2(lb+bh+hl)
      • Volume: lbh
      • Nomenclature: l=length, b=breadth, h=height

    • Cube:

      • Lateral/Curved surface area: 4a²
      • Total surface area: 6a²
      • Volume: a³
      • Nomenclature: a=side of the cube

    • Right Prism:

      • Lateral/Curved surface area: Perimeter of base x height
      • Total surface area: Lateral surface area + 2(area of the end surface)
      • Volume: Area of base x height
      • Nomenclature: -

    • Regular Circular Cylinder:

      • Lateral/Curved surface area: 2πrh
      • Total surface area: 2πr(r+h)
      • Volume: πr²h
      • Nomenclature: r=radius of the base, h=height

    • Right Pyramid:

      • Lateral/Curved surface area: ½(perimeter of base) x slant height
      • Total surface area: Lateral surfaces area + area of the base
      • Volume: ⅓ area of the base x height
      • Nomenclature: -

    • Right Circular Cone:

      • Lateral/Curved surface area: πrl
      • Total surface area: πr(l+r)
      • Volume: ⅓πr²h
      • Nomenclature: r=radius of the base, h=height, l=slant height
