Here you go,
so,
as you know,from stochiometric equation,
See the pic,
In case of moles you can also take volume that I wrote.
Thanks.

C2h2 + 5/202 = 2 co2 + h2O
Burning of 1 mole of c2h2 requires 2.5 mole O2
That means 2.5 x 22.4L = 56000 cm 3 o2
Let total air required be M
20% of air = 56000 cm3o2
20 m/100 = 56000cm3o2
M = 56000 x 100/20 = 280000 cm raise to power 3
