What is a Cube Root (Page 1/7)
Cube is a three dimetional concept, having length, width and height.
In Fig-2-1 all the side of the figure is having 2 unit and the total no of units is 8 (count in figure), therefore it is Cube of 2 i.e. 2*2*2=8 unit
In Fig-2-2 all the sides are having 3 unit and the total no of units is 27 (count in figure), therefore it is Cube of 3 i.e. 3*3*3=27 unit
Now
What is Cube Root: This is reverse calculation to find out units in each direction
Fig 2-1 is having 8 units, and 2 unit is each direction. Therefore the Cube root of 8 is 2.
Fig 2-2 is having 27 units, and 3 unit is each direction. Therefore the Cube root of 27 is 3.
