The document thanks the teacher for giving the opportunity to do a wonderful project that helped increase knowledge. It also thanks parents and friends for their help in finishing the project on time. The purpose of the project was not just for marks but also to gain more knowledge. Thanks are expressed again to all who provided assistance.
this is about surface area and volume to help the students to do there projects or ppts and insure that u can also see this and make another like this so all the best of this ppt for who al cannot do on there own so enjoy this thing here .... and thanks for watching :) ..

Surface area is the sum of total exposed area of a three dimensional solid object. Its unit can be in the form cm2, m2 etc.
Volume is the amount of space occupied by an object. Its unit can be cm3, m3, etc.
topics -
1. Cube, Cuboid and Cylinder
Cuboid: A cuboid is the solid shape which has six rectangle faces at right angles to each other.
Cube: A cube is a special form of cuboid which is bounded by six equal square faces.
Right Circular Cylinder: A solid obtained by revolving a rectangular lamina about one of its sides, is called as Right Circular Cylinder.
2. Cone and Frustum
Cone: A cone is a three-dimensional geometric shape that tapers smoothly from a flat circular base to a point called vertex.
We can also define it as, “A solid obtained by revolving a right angled triangular lamina about
any side (except hypotenuse) is a right circular cone.”
Frustum: If the cone is cut off by a plane parallel to the base not passing through vertex then we get the lower base portion as a frustum of cone.
3. Sphere and Hemisphere
Hemisphere: A plane passing through the center of a sphere divides sphere into two equal parts. Each part is called a hemisphere.
4. Combination of solids
In real life we come across different objects which are a combination of many shapes like cube cuboid, cylinder, sphere, cone etc. In our previous topics we have seen how to find the areas and volumes of simple objects. Now we will look at a few examples on how to find the areas and volumes of combination of solids.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. I would like to express my special thanks of
gratitude to my teacher (name of the teacher),
who gave me the golden opportunity to do this
wonderful Project, which also helped me in doing a
lot of Research and I came to know about so many
new things.
I am really thankful to them.
Secondly i would also like to thank my parents and
friends who helped me a lot in finishing this project
within the limited time.
I am making this project not only for marks but to also
increase my knowledge .
THANKS AGAIN TO ALL WHO HELPED ME.
5. Volume is the measure of the amount of space inside of a
solid figure, like a cube, ball, cylinder or pyramid. It's units
are always "cubic", that is, the number of little element
cubes that fit inside the figure.
The formula for the volume of a rectangular prism is:
Area = l x w x h
where:
l = length
w = width
h = height
7. • Area of rectangle 1= (l * h) +
• Area of rectangle 2= (l * h) +
• Area of rectangle 3= (l * b) +
• Area of rectangle 4= (l * b) +
• Area of rectangle 5= (h * b) +
• Area of rectangle 6= (h * b)
=2(l*b) + 2(h*b) + 2(l*h)
=2(lb + bh + lh)
