the basic difference between Area and Volume is that the space occupied by the two-dimensional figure in a 2D plane is known as an area that is measured in square units, for example, wrapping a gift set. while, the space occupied by a three-dimensional figure in a 3D plane is called volume e.g., water inside a fish tank. it is measured in cube units.
In this article, you are going to learn a complete explanation of the difference between Area and Volume in detail.

Let’s Dive right in…!
we often see plenty of objects in our daily life. some of them occupy volumes while others have an area. but commonly we do not recognize or distinguish them easily. hence, People are often confused regarding the two terms area and perimeter because they look like same when measured or highlight similar meanings from their names. but they are not.
the space covered by a 2D closed plane is known as the area. on the other hand, the space covered by a 3D object in a closed plane is called volume.
What is the definition of Area?
in mathematical geometry, the size of any object is called the area of that object. since it is a two-dimensional region enclosed by a 2D closed figure. we can easily calculate it by using the square formula or simply by multiplying all of the sides of an object.
it tells us how many squares of equal length can fit into a closed figure. we use square units to measure the area in the international system of units. for example, centemiter², milimeter², feet², etc.
How can we find the area of a shape?
as we know that area always deals with flat shapes that has always two dimensions i.e., width and length. a square always has equal 4 sides which means it has an equal length for all its sides. like a square, the ellipse has also equal width and height.
by using a coordinate plane, we can easily divide these shapes into small unit squares. there are multiple square units we use to measure the area such as millimeters, centimeters, etc, weather finding the area of any two-dimensional shape like a rhombus, trapezium, or quadrilateral we can use the known square units.
how to find the Area of Squares and Rectangles
as rectangles and squares are simple shapes that can easily convert into small unit squares, we need only the length and width of these shapes to find the area like:
A= L x W
let us take a real-life example. suppose that we have a rectangle that is 180 meters wide and 300 meters long. what will be the area of that rectangle?
A= L x W
A= 180m x 300m
we can shorten the square formula for more ease. because all sides are equal in length, hence, we can write as A= s². for example, we have a square 45cm long. how can we calculate its area?
A = 45²
How to Find the Area of a Circle?
shapes like circles and ellipses are not considered polygons but involve a radius called “r”. we can find the area of these shapes by using the following formula:
A = πr²
How to Find the Area of an Ellipse?
we can find the area of an ellipse by dividing it into two axes i.e., the major axis and the minor axis. the major axis represented by a and highlights the length while the minor axis highlights the width and is represented as b. by using the formula:
A = πab
Area Formulas for different geometric shapes
|Triangle||1/2 bh (b=base, h=height)|
|Rectangle||l × w (l= length, w= width)|
|Square||l × l (l=length)|
|Trapezium||1/2(a +b)h ( a,b lengths, h height)|
|Parallelogram||b × h (b= base, h=height)|
List of Square units to measure the Area
What is the definition of Volume?
in mathematics, the three-dimensional quantity occupied space by a closed surface or boundary e.g. solid, liquid, or gas is known as volume. for example, a petrol tank can have a capacity in the volume of 10 liters to refuel it.
we use multiple units of cubes derived from SI units like cubic meters, liters, barrels, gallons, etc. to express the volumes of different quantities.
hence, the SI unit for volume is a cubic meter or m³. however, the common unit of volume we use in our daily life is litter (L).
Volume Formulas for different geometric shapes
|Cube||a³ (a= length for all sides)|
|Sphere||4/3 πr³ (r= radius)|
|Cylinder||πr²h (r=radius, h=height)|
|Cone||1/3 πr²h (r=radius, h=height)|
|Rectangular Prism||l × w × h (l= length, w= width, h= height)|
|Cuboid||ABC (a,b,c= length of each side individually)|
