SAT Math Multiple Choice Practice Question 411: Answer and Explanation
15. How many numbers from 1 to 200 inclusive are equal to the cube of an integer?
Correct Answer: E
E Once again, the way not to solve an SAT question is to reason algebraically. Instead, use your calculator to start cubing integers and stop when you find an integer cubed that is greater than 200. 13, 23, 33, 43, and 53 are all less than 200. 63 is 216, so that's too large. Thus there are 5 numbers.
