In Mathematics, Mensuration is a branch that deals with the study of different geometrical shapes and its parameters, such as length, breadth, height, area, volume, and so on. There are various shapes in Geometry, which are classified under any one of these categories, such as
- Two-Dimensional Shapes
- Three-Dimensional Shapes
There is a difference between two-dimensional and three-dimensional shapes. 2D shapes have only length and breadth. It does not have thickness. But, the 3D shapes have thickness. It involves three different measures such as length, breadth and width. All the 2D and 3D figures have a list of formulas that establishes the relationship between the parameters of the specific shape. Here, let us discuss the ways to learn the mensuration formulas quickly.
Once you are familiar with all the formulas of a plane figure, it is easy to determine the surface area and volume formulas for the solid figures. We know that the 3D form of a circle is a sphere. If you are familiar with the circle formula, it is easy to find the surface area and the volume of sphere. Likewise, you can find the formulas for various shapes.
It is easy to learn the formulas for three-dimensional shapes. Since 3D shapes are obtained from the rotation of the 2D shapes, the surfaces of the solids have been a 2D shape. So, the total surface area of any three-dimensional shapes can be obtained by adding all the surfaces of the given figure.
Now, let us discuss how to determine the formulas for the plane figures. The characteristic property of a shape establishes the formulas. For example, let us take two 2D shapes, a square and a rhombus. Both shapes have similar features. All the sides are equal in both square and rhombus. But the angle measures are different in rhombus, whereas all the angles are at right angles in a square. Thus, the area of rhombus is different from the area of a square. If you are clear with the properties of various 2D shapes, you can quickly learn the mensuration formulas for 2D shapes.
