The formula tells you
.. V = constant * T/P
That is, volume is proportional to absolute temperature and inversely proportional to pressure.
When temperature increases from 273 K to 300 K, volume is increased by the factor 300/273.

When pressure increases from 2 atm to 3 atm, volume is changed by the factor 2/3.

The new volume will be
.. (10 L) * (300/273) * (2/3) = 2000/273 L ≈ 7.3 L
