In the introduction part of Class 10 Chapter 13, you would recall what you studied in class IX about solids like a cube, cylinder, cuboid.
You had learned the formulas for finding the surface area and volumes of these solids earlier. We come across multiple objects in our daily lives that are a combination of ncert solutions for class 10 maths ch 13 dig of these shapes. For example, a truck carrying oil which is in the shape of a cylinder that has 2 hemispheres at its end.
In the Surface Area Volume Class 10 you would learn how to calculate the surface area and volumes of such solids which are a combination of two or more solid shapes. The outer part of any 3-D figure is the surface area of that figure. To find out the surface area of a solid which is a combination of solid shapes, we would need to find out the surface area of individual solid shapes separately to find the surface area of the entire 3-D solid shape.
Let us clarify this with an example:. The solid in the figure above is a combination of a cone, cylinder, and hemisphere. The volume of solids Ncert Solutions For Class 10 Maths Ch 3 Ex 3.6 Eng by joining two or more basic solids is the sum of the volumes of individual solids. Let us understand this with an example:. The solid in the above figure is made up of two solids, i. So the total volume of the solid is obtained by adding up the volume of these two constituent solids.
When we convert a solid from one form to another by the method of melting or remoulding, then the volume of the solid stays the same, despite the change in shape. We will see an example to understand why:.
Solution ncert solutions for class 10 maths ch 13 dig From the theorem on volumes, we know that volume of the water in the cylinder and the volume of the water in the cuboid would be the. If the water fills the cylinder to the brim then:. Many students often find it difficult to remember important Mathematical formulas and even in solving textbook exercises. They can list down these formulas and revise them on a regular basis.
Doing this will help students solve the exercises more efficiently. These solutions ncert solutions for class 10 maths ch 13 dig solved in a very simple and step-by-step manner to help the students to understand and solve the problems easily.
These solutions are solved by the expert teachers keeping in mind the basic guidelines of the CBSE Board.
