Introduction

One of the most routine of day-to-day physical units, but one that causes innumerable conceptual misunderstandings, "volume" is visualised here hands-on by making cubes only out of paper.

1. Step 1 Precaution

• Handle scissor with care.

2. Step 2 Step 1 - Making Square Sheets (I)      • Draw a vertical line at 14cm from one end of the sheet.

• At 28cm from the top of the vertical line draw a perpendicular towards the 14cm.

• Now fold along the vertical line.

3. Step 3 Step 2 - Making Square Sheets (II)      • Cut the creased vertical line with the help of a ruler.

• Now fold along the perpendicular line drawn at the bottom initially and cut it off using a ruler.

• Now you're left with a 14cm x 28cm rectangle.

4. Step 4 Step 3 - Square Sheets    • Fold the rectangle laterally and cut across the creased line.

• This gives you two 14cm x 14cm square sheets.

• Repeat Step 1 to 3 for two more A4 sheets ( coloured preferably ) . This way you'll have the required six 14cm x14cm square sheets.

5. Step 5 Step 4- Folding      • Fold the square to make two equal halves.

• Fold the two halves towards the middle to make it look like a cupboard.

• Fold laterally to divide it into two equal parts.

6. Step 6 Step 5-Make a parallelogram    • Fold the upper half towards the center to make the first triangle.

• Fold the lower half towards the center in the opposite direction to make the second triangle.

• This makes a parallelogram.

7. Step 7 Step 6-Open the upper triangle      • You will find a small triangle on your left open.

• Fold it inside

• Tuck the remaining portion on your right inside the left

8. Step 8 Step 7-Open the lower triangle      • Repeat the procedures of step 6 for the lower triangle.

• You'll have a parallelogram with four pockets.

9. Step 9 Step 8-Flaps and Pockets      • Turn around

• Fold the triangles as flaps with a square in the middle.

10. Step 10 Step 9-Make 6 such modules    • Now you have two triangular flaps and a square with four pockets.

• Repeat steps 1 to 5 for the remaining sheets.

11. Step 11 Step 10- Start making the cube      • Take one module and place it as shown.

• Insert the second module's flap into the first module's pocket as shown.

• Insert the third module in the opposite pocket.

12. Step 12 Step 11- Inserting 4th module.      • Tuck the 4th module into the second as shown.

• Turn around.

• Erect the 4th module to 90 degrees

13. Step 13 Step 12-Appropriate tucking      • Do all the possible tucking.

• Turn around such that the cube has it's top uncovered.

14. Step 14 Step 13- Inserting the 5th module      • It should be inserted such that the cube now has it's top covered.

15. Step 15 Step 14- Insert 6th module      • Turn around again to have the cube's top uncovered.

• Insert the 6th module as shown.

16. Step 16 Step 15-Your cube is complete • Tuck every open flap appropriately.

17. Step 17 Observation • What is the length, breadth and height of the cube?

• How many cubes of volume 125ml will be required to make a 1L cube?

• What should be the dimension of square to make one 1L cube?

• How many boxes of 125ml are required to make 1l in horizontal direction?

• How many boxes of 125ml are required to make 1l in verticall direction?

18. Step 18 Observation      • Take a cube and open the lid, seal the cube inside with plastic cover and fill the cube with water

• Now pour the water into measuring cylinder and measure the quantity

• Make your own measuring cylinder

19. Step 19 Troubleshooting

• Folds are not accurate.

• Improper tucking.

• Wear and tear of paper.
