It is not clear whether or not "between" is to be consider to include either or both of those two numbers. In any case, the solution is not too different in each case.
Let's assume that the perfect cube being sought is strictly smaller than the larger of the two numbers given. We take the cube root of that number and round it downward to the nearest integer and then cube it. If that number is greater than (or equal in case "between" is inclusive) to the smaller of the two numbers, then that is the perfect cube being sought. If it is smaller than the smaller of the two numbers, there is no such perfect cube.

How many cube numbers are 2000 and 4000?
To find how many cube numbers are between 2000 and 4000, we first calculate the cube roots of these numbers. The cube root of 2000 is approximately 12.6, and the cube root of 4000 is approximately 15.9. The integer cube numbers within this range correspond to 13, 14, and 15, which are (13^3 = 2197), (14^3 = 2744), and (15^3 = 3375). Therefore, there are three cube numbers between 2000 and 4000.
How do you find a perfect cube?
To find a number that is a perfect cube, take an integer, mulitply it by itself and again. The answer is a perfect cube. Thus n * n * n To find a perfect cube as a 3 dimensional object is not possible. It is a concept that can exist only in your imagination. Any physical representation is bound to have microscopic (or smaller) flaws - certainly at the sub-atomic level.
How can you find irrational number between any two number?
There are infinitely many irrational numbers between any two numbers - rational or irrational.Suppose x and y are two irrational numbers.Consider x2 and y2. Is there any integer between them that is not a perfect square? If so, the square root of that number is an irrational between x and y.If not, consider x3 and y3 and look for an integer between them that is not a perfect cube. If there is then the cube root of that number will meet your requirements.If not, try x4 and y4 and then x5 and y5 etc. In a school exercise you are extremely unlikely to have to go as far as the cubes!
How do you find the perfect cube of a number?
juss countt all the sides'xx !
Formula for volume of a cube?
Length X Width X Height Or if it's a perfect cube, just find one side and cube it.
