no they that can't be done as the boxes are odd in number and the number you've are also odd so odd times odd will be odd this just be done by using factorial like 3! Which is an even number as 1*2*3=6
it can be done by 3!+3!+3!+3!+3!
it can be done by 3!+3!+3!+3!+3!

3! + 3! + 3! + 3! + 3! = 30
==========================
The following are many other ways of getting the solution.
3! + 1 + 3 + 9 + 11 = 30
1 + 5 + 7 + 3! + 11 = 30
3! + 3! + 3! + 11 + 1 = 30
3! + 3! + 11 + 5 + 1 = 30
11+ 1 + 1 + 3! + 11 = 30
15 + 3 + 3 + 3 + 3! = 30
13 + 1 + 1 + 9 + 3! = 30
13 + 1 + 3 + 7 + 3! = 30
13 + 5 + 3 + 3 + 3! = 30
