- Mensuration is a topic in Geometry which is a branch of mathematics.
- Mensuration deals with length, area and volume of different kinds of shape- both 2D and 3D. So moving ahead in the introduction to Mensuration.

- 2D shape is a shape that is bounded by three or more straight lines or a closed circular line in a plane. These shapes have no depth or height. They have two dimensions length and breadth. Therefore called 2D figures or shapes. For 2D shapes, we measure Perimeter (P) and Area (A).
- 3D shape is a shape that is bounded by a number of surfaces or planes. These are also referred to as solid shapes. These shapes have height or depth unlike 2D shapes, they have three dimensions Length, Breadth and Height/Depth and therefore they are called 3D figures. 3D shapes are actually made up of a number of 2D shapes. Also, know as solid shapes, for 3D shapes we measure Volume (V), Curved Surface Area (CSA), Lateral Surface Area (LSA) and Total Surface Area (TSA).

3.It has a wide application in our everyday life. From construction of a house to a bridge, mensuration plays important role.4.Archimedes is remembered as the greatest mathematician of ancient area. He is one of the most famous Greek mathematicians contributed significantly in geometry regarding the area of plane figures and areas as well as volumes of curved surfaces.5.Mensuration is important to help you clear your basics and master this important topic for IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams. We have all studied this topic in high school and know that it is a formula oriented topic.6.The branch of mathematics that deals with measurement, especially the derivation and use of algebraic formulae to measure the areas, volumes and different parameters of geometric figures like

- Cylinder.
- Circles.
- Polygons.
- Rectangles and Squares.
- Trapezium, Parallelogram and Rhombus.
- Area and Perimeter.
- Cube and Cuboid.

Also includes surface area and volume of solids such as cubes, cuboids (rectangular cubes), cylinders, cones, spheres and hemispheres. It is being done in our life in many situations.

**For example**

A Length of cloth we need for stitching,the area of a wall which is being painted,perimeter of the circular garden to be fenced, quantity of water needed to fill the tank.For these kind of activities, we are doing measurements for further needs.

**Cone:**

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex.

**Cylinder:**

A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom.

**Circle:**

A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

**Cuboid:**

In geometry, a cuboid is a convex polyhedron bounded by six quadrilateral faces,

whose polyhedral graph is the same as that of a cube.

**Cube:**

In geometry, a cube is a three-dimensional solid object bounded by six square faces,facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.

**Regular Icosahedron:**

In geometry, a regular icosahedron is a convex polyhedron with 20 faces, 30 edges and 12 vertices. It is one of the five Platonic solids, and the one with the most sides. It has five equilateral triangular faces meeting at each vertex.

**Octahedron:**

An octahedron can be any polyhedron with eight faces. … Heptagonal pyramid: One face is a heptagon (usually regular), and the remaining seven faces are triangles (usually isosceles). It is not possible for all triangular faces to be equilateral.

In geometry, an octahedron is a polyhedron with eight faces, twelve edges, and six vertices. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex. A regular octahedron is the dual polyhedron of a cube.

**Annulus:**

In mathematics, an annulus is a ring-shaped object, a region bounded by two concentric circles. The adjectival form is annular. The open annulus is topologically equivalent to both the open cylinder S¹ × and the punctured plane. Informally, it has the shape of a hardware washer.

**Tetrahedron:**

In geometry, a tetrahedron, also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces.

**Sphere:**

A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball. Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point, but in a three-dimensional space.

**Triangle:**

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
