Unfortunately, there are an infinite number of samples with n = 10 that could have a sum of 480.
Was there any other information? Maybe a standard deviation or variance?

Ah, we can work with that.
The variance for a sample is SS/(n-1). Since we know that variance is 846, and that the sample size is 10, we can use the following formula:
846 = SS/(10 - 1), doing a little algebra, we get:
846 = SS/9
846*9 = SS
7614 = SS
Quick side note - That calculation is for samples. If you're dealing with a population, replace "SS/(n-1)" with "SS/n"
Hope that helps
