At NTP the stabdard conditions are achieved therfore the volume can be calculated for each gas is:
For SO2 => moles * 22.4 => 20*22.4 => 448 l
For O2= > 15*22.4 => 336 l
For SO3 => 10*22.4 => 224 l

Volume of SO3 is wrong because you don't balance the reaction.
Reaction ----2 SO2 + O2 =2 SO3.
No of moles of SO3= 2* 10 moles.
So, volume of SO3 is 2*10*22.4.
