JEE Advanced Important Questions of Three Dimensions Geometry

In mathematics, Geometry is the practical section involving shapes and sizes and different properties of varied materials. The subject of geometry can be classified into two parts- solid and plane geometry. The plane geometry studies shapes that are flat like the lines, curves etc. solid geometry on the other hand is the study of three-dimensional shapes like the cylinder, cube, etc. 

In the case of Cartesian Geometry, one notices that it usually deals with the 2-D and 3-D geometry. On the one hand, two-dimensional geometry encompasses the study of the location from a given x-y plane; whereas three-dimensional geometry deals with the three orthogonal axes, that is, x, y and z axes. Thus, one can state that three-dimensional geometry in brief is simply an extension or the product of the two-dimensional geometry.

Three dimensions in geometry are the solids that possess three dimensions- length, width and height. The 2-dimensional shapes only have two dimensions associated with length and width. Three-dimensional shapes can be seen in the day to day surroundings. A cone-shaped ice cream, a box of cubical shapes etc are examples of the same.  

Geometry is one of the practical sections of Mathematics that involves various shapes and sizes of different figures and their properties. Geometry can be divided into two types: plane and solid geometry. Plane geometry deals with flat shapes like lines, curves, polygons, etc., that can be drawn on a piece of paper. On the other hand, solid geometry involves objects of three-dimensional shapes such as cylinders, cubes, spheres, etc. In this article, we are going to learn different 3D shapes models in Maths such as cube, cuboid, cylinder, sphere and so on along with its definitions, properties, formulas and examples in detail.

This article by Vedantu will focus on the three-dimensional geometry, called solid geometry,  that forms the syllabus of the JEE advanced examinations. The study of solid geometry will deal with the different shapes such as cubes, cuboids, tetrahedrons, etc. As Three Dimensional geometry is one of the most important topics for the JEE aspirants, this article will provide the candidates with important questions that will help them prepare better for the exam.

Three Dimensions Geometry Important Questions for JEE Advanced

This chapter is also known as solid shapes. The common 3D shapes are cube, cuboid, cylinder, sphere, prism, cone, frustum, etc. The various properties of these 3D solid shapes are important to remember. The JEE Advanced Three Dimensions Geometry important questions are mostly applications of the properties of these solid shapes. The basic formulae for these shapes include formulae for volume, lateral surface area, and total surface area. JEE Advanced aspirants get a proper grasp on this long list of formulae for solid shapes with practice. There are several properties, solving for the proof of which are included in the syllabus of 10+2 boards. 

Among all the solid shapes, spheres, cylinders, cones are mostly included in the syllabus of Class 10 board exams as well. 

JEE Advanced important questions on Three Dimensions Geometry and their solutions are provided in the PDF  given below. Aspirants may download the PDF and make a self-assessment, by referring to the solutions. Practising these questions within a given time limit will help JEE Advanced aspirants to improve their pace.

FAQs on JEE Advanced Three Dimensions Geometry Important Questions

1. Is 3-D geometry important for JEE advanced?

Yes, the topic of 3-D geometry is very important for the students aspiring to sit for the JEE Advanced examinations. The question paper of the JEE Advanced presents lots of questions from this particular chapter. If the student is not prepared well with the contents of this chapter, there are high chances that he/she might lose marks which might affect his ranking.
