its 7 because 7*7=49 and 49*7=343
so the cube root of 343 would be 7
If the order of the numbers in the question are the order Darrin put theem in then no, his work is not correct. this is because 7.25 is not greater than 7.52. the real order should be 7.52,7.25, 5.72, 5.27
The answer is table D as it is the only one without a repeated input ❤️ hope that helps
