Alcohol from potatoes

In the distillery, 10 hl of alcohol can make from 8 t of potatoes. The rectangular field with dimensions of 600 m and 200 m had a yield of 20 t of potatoes per hectare. How many square meters of area are potatoes grown to obtain one liter of alcohol?

Correct result:

x =  4 m2

Solution:

v=20 t/ha v2=v 1000/10000=20 1000/10000=2 kg/m2  l=10/8=54=1.25 hl/t l2=l 100/1000=1.25 100/1000=18=0.125 l/kg  V=1 l m=V/l2=1/0.125=8 kg  x=m/v2=8/2=4 m2
