The product of three consecutive odd integers is 1287. What is the sum of the three integers?
The numbers are 9 x 11 x 13 so their sum is 33.
The way I did it was to use my calculator to get the cube root of 1287 which was 10.877 • • •
Since it was the cube root, I knew it was close, so I tried the sum starting with 9 and got it the first try.
