Answer:
What are the applications of surface area and volume?
Surface area can be used for finding out things that are proportional to the surface area. Examples are:
How much paint will it take to cover the object.
How much wallpaper it takes to paper a room .
How quickly will the object lose or gain heat. (Especially if you know the volume as well) . By reducing the surface area relative to the volume (say by curling up in a ball) you stay warmer in cold weather.
How much material you need to make an item of clothing.
How many materials you need to clad the outside of a building or tile a roof.
Volume:
Useful for knowing how much stuff fills a space. Examples:
How much water fills a swimming pool.
How many cups a tea from a teapot.
How much helium to fill a balloon.
How much of the things you need to build anything, as anything can be broken down into many solid components.
How heavy will something be.
How much stuff there is, eg how much sand in a heap.
