Area vs Volume

As we know that geometry is the study of shapes. It deals with plane shapes and solid shapes. We calculate different terms associated with the shapes, like length, width, height, area, perimeter, volume, etc. Area and volume are the two important concepts used in our daily life. We see many shapes around like squares, rectangles, circles, polygons, etc. Every shape has its unique properties and measurements. Hence every shape has a different area and volume, based on their measurements. So here on this page, we will study the difference between area and volume in Math and formulas associated with different shapes.

Area

The area is the measurement of the region covered by any two-dimensional geometric shapes. The area of any shape depends upon its dimensions. Different shapes have different areas. For instance, the area of the square differs from the area of the rectangle. The area of a shape is calculated in square units (sq units). 

Suppose if you want to paint the rectangular wall of your house, you need to know the area of the wall to calculate the quantity of the paint required to paint the wall and the cost of painting.

If two figures have a similar shape it is not necessary that they have equal area unless and until their dimensions are equal. Suppose two squares have sides s and s1, so the areas of the two square will be equal if s = s1

Volume

The space occupied by the three-dimensional object is measured in terms of the volume of that object. The volume of a solid shape is the product of three dimensions, so the volume is expressed in cubic units. Suppose the volume of a cube is measured by the product of its length, width, and height.

The interior of a hollow object can be filled with air or some liquid that takes the shape of the object. In such cases, the volume of the substance that the interior of the object can accommodate is called the capacity of the hollow object. Thus we may say that the volume of an object is the measure of the space it occupies and the capacity of an object is the volume of the substance its interior can accommodate.

Area vs Volume Definition

The area refers to the region covered by the object. And volume refers to the quantity or capacity of the object. An area is a two-dimensional object whereas volume is a three-dimensional object. The area is a plain figure while volume is a solid figure. The area covers the outer space and volume covers the inner capacity. The area is measured in square units and volume is measured in cubic units. 

Generally, the area is calculated for two-dimensional objects, while volume is calculated for three-dimensional objects.

Here is the pictorial representation of area and volume which shows the relation between area and volume.

Difference Between Area and Volume

Some of the key difference between area and volume in math are:

Area vs Volume

These differences show the relation between area and volume. As now the difference between area and volume in math is clear, let us solve some examples.

Solved Examples

Example 1:

The sides of a square plot is 9m.  Find the area of a square plot.

Solution:

Given, Side = a = 9m

By the formula of area of a square, we know that

Area = a2

A = 9 x 9

A = 81 sq.m.or 81m2

Example 2: The side of the cubic box is 9m. Find the volume of a cubic box.

Solution:

Given, Side = a = 9m

By the formula of volume of a cube, we know that

V = a3

V = 9 x 9 x 9

V = 729 sq.m or 729m2
