use combination to find the ways nCr

$nCr= \frac{n!}{r!(n-r)!}$

$6C2= \frac{6!}{2!(6-2)!}=15$

2 different sides can be selected from 5 different side orders in 5C2 ways

$5C2= \frac{5!}{2!(5-2)!}=10$

3 different flavor drinks can be selected from 8 different flavor drinks in 8C3ways

$8C3= \frac{8!}{3!(8-3)!}=56$

2 ice cream flavors can be selected from 8 ice cream flavors in 8C2 ways

$8C2= \frac{8!}{2!(8-2)!}=28$

Total ways = $15 \cdot 10 \cdot 56 \cdot 28=235200$
