Mensuration

➥ Mensuration is the branch of mathematics that deals with the measurement of geometric figures like 2D shapes (areas) and 3D objects (surface area and volume).

Important Terms in Mensuration

  1. Perimeter: The total length of the boundary of a closed figure.
  2. Area: The space enclosed within a 2D shape.
  3. Volume: The space occupied by a 3D object.
  4. Lateral/Curved Surface Area (LSA/CSA): The area of all the sides of a 3D object excluding the top and bottom.
  5. Total Surface Area (TSA): The total area covered by the outer surfaces of a 3D object.
