Activity 8: Maximum Volume of an Open Box
Objective:
To construct an open box with the maximum volume from a given rectangular sheet by cutting equal squares from each corner.
Method of Construction:
- Take a rectangular chart paper of size 20cm x 10cm and name it as ABCD.
- Cut four equal squares, each of side x cm, from each corner A, B, C, D.
- Repeat the process with the same size chart papers and different values of x.
- Make an open box by folding its flaps using sellotape.
Demonstration:
- When x=1, Volume=144 cm3
- When x=1.5, Volume=178.5 cm3
- When x=

Sound: Production, Propagation, and Applications
How Sound Reaches Your Ear
Sound Production and Propagation
Sound is produced by vibrating objects, causing surrounding particles in a medium to vibrate as well. This creates a disturbance that travels as waves, ultimately reaching our ears.
Examples of Sound Production
School Bell
When a school bell is struck, it vibrates back and forth, generating compressions and rarefactions in the air. These pressure variations constitute sound waves.
Mechanical Waves
Sound waves are classified as mechanical waves
