The cubes essentially refers to the multiplication of a specific number 3 times. Cube roots, in contrast, are the exact opposite. So for instance, a cube of 5 is the multiplication of the number cube three times and it gives the result 125. In contrast, the cube root of 125 gives us the number 5. To put it in a different way, 5 is multiplied by three times and thus gives us the specified number. Memorising cubes all the way from 1 to 20 and similarly cube roots from 1 to 21, would assist us in calculating faster as well as more efficiently.
Cubes from 1 to 20
The cubes from 1 to 20 and the cube root of 1 to 20 is important and should be memorised by the students. Memorising it helps with faster calculations and removes the need of manually going through tedious and long calculations. If anyone has memorised the cube table then finding the cube or cube for a number such as 64 would be incredibly easy and they wouldn’t need to do explicit calculations for finding the answers. This is an extremely efficient technique and should be used by all the students.
Here we will be listing the cube root of 1 to 20 in a tabular format. This will help the students in solving questions faster and with considerably more ease. The cube roots are included upto 3 decimal points.

Learning this table will help the students to break down the complex calculations in simpler terms and use their memory for doing these calculations efficiently and easily.
Now we will be listing the cube values of 1 to 20 in tabular format.
