Formula to find Area and Volume
Define Area:
Area is the size of a two-dimensional surface.he mathematical term 'area' can be defined as the amount of two-dimensional space taken up by an object. This lesson will define area, give some of the most common formulas, and give examples of those formulas.
Define Volume:
It is the size of three dimensional surface. Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, etc. It's units are always "cubic", that is, the number of little element cubes that fit inside the figure.
Rectangle :
In two dimension
area : l x b
l = length
b= breath
In Three dimension:
Triangle:
In two dimension
area=bh/2
l=length
b=breath
h=height
In Three dimension:
Circle:
In two dimension
r=radius
π=22/7
r=d/2
d=diameter
In Three dimension:
