The value of cube root from 1 to 30 will help not only Class 8 but also higher class students to solve mathematical problems. List of cubic roots of natural numbers 1 to 30 is provided herein a tabular form. Apart from these, students should also memorise the cubes from 1 to 15 to solve the problems easily and quickly. Also, check Cube Root Of Numbers.
The cube root has many applications in Maths, especially in geometry where we find the volume of different solid shapes, measured in cubic units. It will help us to find the dimensions of solids. For example, a cube has volume ‘x’ cubic meter, then we can find the side-length of the cube by evaluating the cube root of its volume, i.e., side = 3√x. Let us see the values of cubic roots.

Solved Examples
Q.1: Solve 3√5+3√8.
Solution: From the table, we can get the value of 3√5 and 3√8
3√5 = 1.70997.. = 1.71 (Approx)
3√8 = 2
Therefore,
3√5+3√8 = 1.71+2 = 3.71
Q.2: Solve 3√30 – 3.
Solution: We know,
3√30 = 3.1072
Therefore,
3√30 – 3 = 3.1072 – 3 = 0.1072
Q.3: Evaluate the value of 53√9.
Solution: We know,
3√9 = 2.080
Therefore,
53√9 = 5 x 2.080
= 10.4
