    I'm not sure what you're asking. Do you want to know how to do it with or without a calculator?

    the unit value of an integer will map to a definite unit value when cubed: 0-0 1-1 2-8 3-7 4-4 5-5 6-6 7-3 8-2 9-9 so you know half the number off the hop. which ever 10's cube it lay between is your answer

    No the main condition is ..I can tell u cube root of that number which is obtained by multiplying three times a number that lie between 1 to 100 and the number which u r multiplying must be positive Integer !
