# two types of barrel question

Classical Mechanics Level pending

Two types of barrel units are in use in a town: the apple barrel and the cranberry barrel. The apple barrel has a legally set volume of $$120 \text{ L}$$ while the cranberry barrel has $$87 \text{ L}.$$ If a merchant sells $$20$$ cranberry barrels of goods to a customer who thinks he is receiving apple barrels, what is the discrepancy in the shipment volume in $$L?$$
