4th Maths : Term 3 Unit 3 : Measurements - Recall
A one dimension quantity − length. Two dimension quantity − length and breadth. When we expand 1 cm from the surface of 2D, it forms 3D. Three dimensional quantity is called as volume.
UNIT−3 MEASUREMENTS
Recall: Volume
A one dimension quantity − length and it is represented as
Two dimension quantity − length and breadth. Which can be represented as
The space ocupied here: \( 1\text{cm} \times 1\text{cm} = 1 \text{cm}^2 \).
Two dimensional quantity is called as Area.
Definition of volume
When we expand 1 cm from the surface of 2D, it forms 3D.
The space occupied here: \( 1\text{cm} \times 1\text{cm} \times 1\text{cm} = 1 \text{cm}^3 \).
Three dimensional quantity is called as volume.
So, volume is the space occupied by any 3D object (cone, cube, cuboid and cylinder).
