The cube of 3 is just 3 cubed, which is 3 x 3 x 3, which equals 27
Therefore the sum of them is 25 + 27 = 52
Basically, all this means is what prime numbers would you multiply together to make the number. For example, with 48:Quote:

48 can be split into 24 and 2
24 can be split into 12 and 2
12 can be split into 4 and 3
4 can be split in 2 and 2
Therefore, 48 = 2 x 2 x 2 x 2 x 3
Which can also be written as 2^4 x 3
I hope this makes sense :)
