Calculate the ending inventory if the company uses LIFO method

March		1		Beginning inventory 1,950 liters at a cost of 60 per liter.
March		3		Purchased 2,475 liters at a cost of 65 per liter.
March		5		Sold 2,320 liters for $1.10 per liter.
March		10		Purchased 3,820 liters at a cost of 72 per liter.
March		20		Purchased 2,580 liters at a cost of 80 per liter.
March		30		Sold 5,160 liters for $1.25 per liter.

I got

03/05 COGS -> 2320(.65)= $ 1508

03/30 COGS -> 2580(0.80)+2580(0.72)= $ 3921.6

TOTAL COGS= $ 5429.6

ENDING INVENTORY= 7593.15-5429.6= $ 2163.55

WHY IS THIS WRONG?
