Explanation:

Before you find the actual answer, explore what you know about the number..

#1^3 =1#
#2^3 =8#
#3^3=27#
#color(white)(xxxxxx)larr# 30 fits in here
#4^3=64#

We can see the the number we are looking for is a number between #3 and 4#.

The answer will not be a whole number,

The opposite operation to cubing is finding the cube root:

#x^3 = 30" " x = root3 30#

#x = 3.107232506.....#

The answer is an irrational number, an infinite non-recurring decimal.
