Read and download area and volume formula for std 6to8 in pdf file in Gujarati.
Area is the size of a two-dimensional surface. This lesson will define area, give some of the most common formulas, and give examples of those formulas. A quiz at the end of the lesson will allow you to work out some area problems on your own.
Definition of Area
The mathematical term 'area' can be defined as the amount of two-dimensional space taken up by an object. The use of area has many practical applications in building, farming, architecture, science, and even deciding how much paint you need to paint your bedroom.
Volume is defined as the 3-dimensional space enclosed by a boundary. In this lesson we will define volume, give some of the most common formulas and then work some example problems to become familiar with the formulas. There will be a quiz at the end of the lesson for practice.
Definition of Volume
Volume is defined as the amount of space taken up by an object. It is most often described in terms of meters cubed (m^3). One way to find the volume of an object is to completely submerge the object in water and measure the volume of water that is displaced by the object. The amount of water displaced is equal to the volume of the object. If you don't happen to have a large amount of water handy, or the object you are interested in would not fare well in water, there are formulas you can use instead. Determining the volume of cubes or rectangular prisms can be found quite easily. You can also determine the volume of more complex shapes such as cones, pyramids, cylinders or spheres.
Determining the volume of an object can be of practical importance. Knowing the volume of an object can help you determine how much would be needed to fill that object, like the amount of water needed to fill an aquarium.
