## FAQs on Introduction, Basic Concepts & Formulae: Mensuration- 1 Video Lecture - CSAT Preparation - UPSC

 1. What is mensuration and why is it important in mathematics? Ans. Mensuration is a branch of mathematics that deals with the measurement of geometric figures and their parameters such as area, volume, and perimeter. It is important in mathematics as it helps in understanding and solving real-life problems related to measurement, construction, and design.
 2. What are the basic concepts of mensuration? Ans. The basic concepts of mensuration include understanding the concepts of length, area, volume, and perimeter. Length refers to the distance between two points, area refers to the measure of surface covered by a figure, volume refers to the measure of space occupied by a figure, and perimeter refers to the distance around a closed figure.
 3. What are the formulas for finding the area of different geometric figures in mensuration? Ans. The formulas for finding the area of different geometric figures in mensuration are: - Rectangle: Area = length × width - Square: Area = side × side - Triangle: Area = 1/2 × base × height - Circle: Area = π × radius^2
 4. How do you find the volume of different 3D shapes in mensuration? Ans. The volume of different 3D shapes in mensuration can be found using the following formulas: - Cube: Volume = side × side × side - Cylinder: Volume = π × radius^2 × height - Cone: Volume = 1/3 × π × radius^2 × height - Sphere: Volume = 4/3 × π × radius^3
 5. How is mensuration used in real-life applications? Ans. Mensuration is used in various real-life applications such as construction, architecture, engineering, and design. It helps in calculating the materials required, estimating costs, designing structures, and measuring quantities accurately. For example, mensuration is used in calculating the area of a field, determining the volume of a container, or designing the layout of a room.
