About NCERT Chapter 13 Ex 13.5

NCERT Class 12 Maths Chapter 5 Exercise 5.6 deals with Parametric equations. In this exercise, we will learn how the volume and surface area of cuboid and cube shapes can be calculated. All the students of Class 9 must know the fact that a cuboid is having six rectangular faces where the length, breadth, and height vary, and on the other hand, a cube is having six surfaces having the same length, breadth, and height. Word Problems given in the same exercise will serve to inculcate the ideas of how the two can be calculated and these are having some real-life applications.

For example, Numericals are given as to how much volume of water will be poured out when a certain volume of any substance or other material is poured in. Other questions pertain to the questions which include finding out the ratios of surface areas and more.

Tips and Tricks to Solve Class 9 Maths Ex-13.5

Since you have got the solution for class 9 maths ex 13.5, let us give you some essential tips and tricks for solving this exercise.

Get a Rubik’s Cube: Since the exercise deals with cuboid and cube problems, it is very much easy to use a Rubik’s Cube. This will help in idealising the concepts of all the lengths, breadths, and heights of the geometrical figures. Furthermore, solving numerical of ex 13.5 will become easier when Rubik’s Cube is used since it also boosts the memory power of the students.

Learn the Volume concepts: Know all the conversion formulas along with the volume concepts which are needed for solving the questions from this exercise. Furthermore, a quick tip is the volume units are always expressed in cubic meters/centimeters of liters/milliliters. So, knowing the conversion multiplication/division factors is very much essential.

Here we have given some of the most common used conversion factors:

• 1 kilo = 10³ base unit
• 1 deci = 10^-1 base unit (10 deci = 1 base unit)
• 1 centi = 10^-2 base unit (102 centi = 1 base unit)
• 1 milli = 10^-3 base unit (10³ milli = 1 base unit)
• 10³ micro = 1 milli (1 micro = 10-3 milli)
• 1 cm³ = 1 mL = 1 cc

Practice, Practice, and Practice: The most you will practice, the more you will excel. Test series and mock test questions should be solved by all the students since this will definitely help in solving all the word problems and they will get a good grasp of the exercise.

NOTE: Using finger tricks can help students a lot in solving all the Mensuration problems. Students must always use the formulas for the respective questions which are asked in the exercises.
