[SOLVED] Thermodynamics problem

DBXO

A gas expands at a constant pressure of 200 kpa from a volume of 10 liters to a volume of 18 liters, how much work was done by the gas on its surroundings?

I believe you would use the equation W = p delta v but i dont think the units are what they supposed to be. What do i need to convert?

Am i overthinking this?

I am an idiot and overthaught it

w = p delta v
8 * 200 = 1600J
