## FAQs on RD Sharma Class 11 Maths Solutions Chapter 12 - Mathematical Induction(By RD Sharma)

**1. What's 3D geometry?**

In geometry, a three-dimensional shape is defined as a solid object or a shape that has three dimensions. I.e; length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. The terms of a three-dimensional figure are faces, edges and vertices. The three dimensions compose the edges of a 3D geometric shape. A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us.

**2. What are the three dimensions of the 3D shape?**

Dimension in this chapter is defined as the measure of the size or distance of an object in one direction which means it is the measurement of the length, width, and height of anything. An object can be One-dimensional or 1D, Two-dimensional or 2D, or Three-dimensional or 3D. In geometry, three-dimensional shapes are solid shapes that have three dimensions. A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height. The three dimensions in 3D are length, width, and height.

**3. In 3D, how many planes are there?**

The coordinates have three axes that define the three planes of the coordinates. In three-dimensional space, a plane can be defined by three points it contains, as long as those points are not on the same line. Some planes are given below as an example

The xy-plane is the plane comprising the axes x and y;

The yz-plane includes the axes y and z;

The xz-plane contains the axes x and z.

These three planes of coordination divide space into eight bits, known as octants.
