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?
