Some practical real world examples why surface area is important:
- If you want to paint a house, you need to know the surface area to determine how much paint to buy.
- If you want to plant grass on a dirt lot, you need to know the surface area to determine how much grass seat to use.
- If you want to sew a dress, you need to know the surface area of the dress (dress size) to know how much material you need.
- If you want to make money mowing lawns, you need to know the surface area of the lawn to know how much to charge for the work.
- If you want to put carpet in a living room, you need to know the surface area of the room to know how much carpet you will need.
- If you are making a label for a soup can company, you will need to know the surface area of the can.

What is a real world example of surface area?
A practical need to calculate surface area arises, for example, when you need to paint your house. The amount of paint you need is proportional to the surface area you want to paint.
What is difference between BET and Langmuir surface area?
BET surface area testing principle is from 3 men names, Langmuir is from one. Usually BET surface area mean multi-layer adsorption, but Langmuir refers to monolayer adsorption. BET surface area principle reflects the real adsorption situation an process for most materials, so, be treated more important and trustable than Langmuir surface area. There area some analyzers( e.g. V-Sorb 2800S, V-Sorb 4800) can test both BET and Langmuir, also with pore size related, you can ask from them for a free test, because our insitutes got one already.
Can the area of a square be negative?
not in the real world. The area of a square = The length of a side, squared. Any number squared is positive.
When in the real world would you ever need to know how to find the area or perimeter of a figure?
Laying turf then fencing it in
What is the surface area of a sphere whose diameter is 18 cm?
Oh, dude, you're hitting me with some math here. So, the formula for the surface area of a sphere is 4πr², where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plug that into the formula, and you get a surface area of 1017π cm². But like, who's really gonna measure that in real life, am I right?

What are example of surface area and volume in real life?
Solid objects exist in real life. Each one of them has a surface area as well as a volume.
What is a real-world situation in which you would find the surface area of a cylinder?
You would need to know the surface area of a cylinder if you are a factory worker at Pepsi. You would need to know the dimensions of the label, so it will fit on the can.
Why knowing how to find the area of an irregular shape is important?
In real life, things do not always have a neat geometric shape. Chemical processes in living organisms depend on the surface area of cells or organs. these are of irregular shape. For example photosynthesis in trees depends on the surface area of leaves. All leaves have irregular shapes.
Why would you need to find area?
If you need to find how big something 2-D is you need to know how to find the area of various shapes. If carpeting you need area. You don't think about it but area is very important. Math isn't useless and is very important int he real world.
Why are formulas important in the real world?
pythagorean therom (a squared plus b squared = c squared), and basically all perimeter and area formuals
What is another real-world flat surface that goes on forever?
There is no real world flat surface which goes on forever. It is a geometric idealised concept. So, since there is not even a first such thing, there cannot be another.
How do you calculate the surface area of earth?
The earth is nearly a spherical object and its surface area = 4*pi*radius2
Would a frog's lung surface area be the same as a human's lung surface area?
In the real life sense no, but if you make our bodies the same size our lungs would be relatively the same size.
Why are 1D figures important in the real world?
1D figures are important in the real world because if we did not have 1D figures, the we wouldn't be able to make 2D and 3D figures.
How is surface area used in real life?
I might want to find the surface area of a box if I were trying to wrap it as a birthday present, that way I'd know how much wrapping paper I would need.
