Any number bigger than 7.37 and smaller than 8.43 will do that. There are an infinite number of them.
9 12 34
63 = 216 OR 73 = 343.
The cube of 9 is 729, as a few moments of calculation would have shown you.
How about 73 = 343 or 63 = 216
How about 8 cubed = 512
729
try maths.com but otherwise its 36
216 = 6 x 6 x 6
