Telanagana State Board Class 6 Science Chapter 13 Learning How to Measure Solution:
Question Number 1: What is the smallest distance that you can measure with a centimetre scale?
Ans. The small distance or unit that can be measured in the centimeter scale is 0.1 cm.
Question Number 2: Are we able to measure the thickness of a metal wire using a scale? Explain.
Ans. No, because its cilindrical in shape. The thickness is measured by screwgauge.
Question Number 3: A school hall measures 20 m in length and 15 m in breadth. Find its area.
Ans. Length = 20 m.
Breadth = 15
So Area is = 20 x 15 m (Length x Breadth)
= 300 meter square.
Question Number 6: Millilitre is a unit for measuring ____
Ans. Volume of Liquids.
Question Number 7: For measuring long distances we can use _____ as a unit.
Ans. Kilomiters.
Question 8: What method will you adopt to measure the volume of a banana? Explain?
Ans. Cubic Centimetre is a standard unit for measurement of volume of solids.
Here we measure the volume of a banana.
At first calculate the number of bananas. Suppose each banana has measurement of 1 cm length, 1 cm breadth and 1 cm height, the volume of each banana is equal to 1 cm x 1 cm x 1 cm = 1 centemeter cube which is known as 1 cubic centimeter and written as 1 cm3. In this way we can measure the volume of banana. That means we can say volume of banana = Length x Breadth x Height.
Question 9: Identify incorrect statements among the following and rewrite them with necessary corrections :
a) One square metre is equal to 10,000 square centimetres.
=> One metre square is equal to 10000 square centimetres.
b) The appropriate unit for reporting the volume of a cylindrical rod is cm2
=> The appropriate unit for reporting the volume of a cylindrical rod is cm3
c) The appropriate instrument to measure the thickness of a 25 paisa coin is a tailor’s tape.
=> The appropriate instrument to measure the thickness of 25 paise coin is a scale or micrometer (its better than scale).
d) A measuring cylinder can directly measure the volume of solids.
=> A measuring cylinder can directly measure the volume of liquids.
Question 11: How will you measure the area of your palm using graph paper? Explain.
Ans. Measuring area of palm by graph paper –
(i) Put your palm flat on the graph paper with no space in between.
(ii) Now draw outline of the palm with the help of pencil.
(iii) Measure total number of squares covered in this area.
(iv) Total area of palm is calculated by surface area of palm = no. of square x area of each square.
* One regular graph paper area of each square is usually 1 cm^2.
Question 13: A carpenter who makes wooden furniture, needs accuracy in measurments. Do you ever notice how he measures? How would you appreciate him?
Ans. A carpenter who makes wooden furniture, needs accuracy in measurements. Carpenter need to measure the distance of the wooden block. So he will definitely use measuring tape or scale. This measuring tape may be in the units of an inch, meter, centimeter , milimeter. He will use the measuring tape as per his needs. Large units of tapes to measure big wooden block and small unit of measuring tape to use small blocks.
Question 14: Make a visit to panchayat office collect information how VRO measure areas of agricultural lands in your village. Prepare a questionaire for this.
Ans. (i) What is the width and length os the land?
(ii) Is these lands in shape square or rectanular?
(iii) How is area of agriculture land calculated?
(iv) What is standard unit of measuring agricultural land?
Question 15: Collect any invitation card with envelope. Find out the difference between the measurments of card and cover. Write down the process that you follow.
Ans. Most of the invitation card are not that long. Then area can be easy found out with the help of a riuler or a measuring scale.
The card is in rectangular form and we know that the area of a rectangle is equal to length multiplied by the width.
So, we need to find out the length and width and multiply both to get the area.
Suppose, The area of invitation card
= 6″ x 4″ = 24″.
Question 16: The distance between numbers in a clock is accurately same. List out the things that you observe in your surroundings with accurate distance between them.
Ans. The things in our surroundings with accurate distance between them, are as follows –
(i) The distance between two respective milestone.
(ii) Equal distance between two lamp post.
(iii) Poles of the road.
(iv) Buttons on a shirt.
(v) Fans wings.
(vi) Distance between the tw wings of planes of same model etc….
Question 17: Try to imagine the area of CD, sim card, mobile phone then find out the area of the above by using graph paper. Compare the values of your guess with graph paper measurment. Which thing is closely related to your guess?
Ans. We know sim card are really tiny as compared other things. When we will put it on graph paper, we will get its area by marking the divisions which comes out to be 25 mm x 15 mm. It ia quite close to our guess.
