RD Sharma Class 6 Maths Solutions Chapter 16 - Understanding Three Dimensional Shapes

Three-dimensional shapes can be measured in three directions; these shapes are also known as solids. Three-dimensional shapes consist of three dimensions, which are height (or thickness or depth), width and length. The thickness in these shapes makes them different from two-dimensional shapes. 

Class 6 Three Dimensional Figures - Edges, Vertices and Faces 

There are three attributes in a three-dimensional figure - edges, vertices, and faces. The faces are the flat surface of a three-dimensional shape. Edges are the point where two faces meet and three edges together make a vertex. The naming of the three-dimensional shapes is as follows-

1. Cuboid - A rectangular prism whose faces are of rectangle shape is called a cuboid. All the angles of the cuboid are 90 degrees. A cuboid has 8 vertices, 12 edges, and 6 faces.

2. Cube - A solid shape that has 6 square faces is called a cube. A cube has 8 vertices, 12 edges, and 6 faces. All the edge lengths are equal in the cube.

3. Cylinder - A geometrical figure that has two circular faces joined by a curved surface is called a cylinder. A cylinder has no vertex, 2 edges, 3 faces (two flat faces and one curved face).

4. Cone - A geometrical figure that has a circular base and a single vertex is called a cone. A cone has one vertex, one edge, one flat face, and one curved face. 

5. Sphere - A perfectly round in shape that has every point on its surface equidistant to the centre is called a sphere. A sphere has no vertex, no edges, one curved face.

6. Prism - A three-dimensional figure that has two equal ends, and a flat surface, also has an identical cross-section across its length is called a prism. A prism has six vertices, nine edges, and five faces.

7. Pyramid - A solid shaped figure that has triangular faces and meets at a point on its top is called a pyramid. The base of the pyramid can be of any shape like a square, triangle, or quadrilateral. The number of E, V, F depends on the base shape.

At Vedantu, students can also get Class 6 maths revision notes, formulas and important questions. Students can also refer to the complete syllabus for the class 6 Maths sample paper and previous year question paper to prepare for their exams to score more marks. Students must go for textbook solutions for the RD Sharma for class 6 chapter 16 as the book is highly recognized by the top teacher even Vedantu’s best faculty also refers the book to their students. The solutions are given step by step, so the students can easily understand each solution without any confusion. 

Students can also find the PDF for the textbook solutions at Vedantu’s official website. They can register themselves for free and can get the free PDF of Chapter 16 - Understanding Three Dimensional Shapes because it is an important subject, as it consists of solids that are of three dimensions that are height, length, and width.
