The document contains geometric formulas for calculating the surface areas and volumes of various 3D shapes including:
- Cuboids: Surface area is 2(lb + bh + hl) and volume is l x b x h
- Cubes: Surface area is 6a^2 and volume is a^3
- Cylinders: Curved surface area is 2πr(h+r), circular base area is πr^2, and volume is πr^2h
- Cones: Curved surface area of a sector is πrl, total surface area is πr^2 + πrl, and volume is 1/3πr^2h
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 :) ..
about daliy life using math in this ppt you will learn about volume and suraface area etc.3d shapes and many more new thing you can learn from this ppt

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.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
4. Area of rectangle 1 = (l x h) +
Area of rectangle 2 = (l x h) +
Area of rectangle 3 = (l x b) +
Area of rectangle 4 = (l x b) +
Area of rectangle 5 = (b x h) +
Area of rectangle 6 = (b x h)
=2(l x b) + 2(b x h) + 2(l x h)
=2(lb + bh + hl)
5.
6. h
Base area = l x b
Height = h
So, Volume of a cuboid

8. Area of square 1 = a xa
Area of square 2 = a xa
Area of square 3 = a xa
Area of square 4 = a xa
Area of square 5 = a xa
Area of square 6 = a xa
Surface area = Area of all six faces
= 6a2

Circular Curved
surfaces surface area
Area of curved surface + Area of two circular surfaces
=(2 π r) x( h) + 2 π r2
= 2 π r( h+ r)

15. Area of circular base =
π r2
Height = h
So, Volume of a
cylinder
= π r2 x h
