Perpendicular distance i believe
Think it's B or A if they want it simplified.
There is 1000 milliliters in a liter. So we're gonna work with thirds. One third is already filled, so that means two thirds is not . So 4 liters fills up 2/3 which we can infer that 2 liters fills up one third of the area... so there is 6 liters in total. Which means there is a total of 6000 milliliters of paint.
