Problems in measurements are very common problems that are mostly encountered while doing math calculations on a daily basis. This part of measurement can be broadly classified into three types of problems:
1.Distance : It generally includes problems with mm, cm, km...
2. Time: It generally includes problems with seconds, minutes, hours...
3.Mass: It generally includes problems with Milli gram, gram, kilo gram...
This part is specially designed for Grade VII and now, we will move to word problems measurement:
Problems 1: If One liter is equal to 1000 cubic centimeter and we have a Milk container containing 34.6 liters of milk, how much does this in cubic centimeters?
Solution 1: 1 Lit = 1000 cc.
34.6Lit = 34.6 * 1000 = 34600 cc.
Problem 2 : If we increase the Radius of a circle by 200 %, how many times will the area be increased for that particular circle?
Solution 2 : Area of circle = ∏r>2. That is the area is directly proportional to the square of the value of radius, when we increase the value of the radius by 200 % that means that now the radius is 3r from earlier r and when we square this 3r it will give us 9r>2, making the value of circle increase by 9 times.
Problem 3: It takes 30 minutes to pile up the bundle of 100 files, there are 2000 files in the store room. How much time will it take? (know more about cbse sample papers, here)
Solution 3: It takes 30 min to pile 100 files, which means to pile 1000 files it will take 300 min and similarly to pile 2000 files it will take 600 minutes, which is equal to 10 hours.
Thus we, hope that now things related to this topic are more clear with the pupils. In the next session we will discuss about Formulas for measurement.
