Answer:
≅ [tex]1.206*10^{-5}[/tex] gallons of water per year
Step-by-step explanation:
knowing that 1 gal = 231 in3 and 1 Ton = 2204.62 pound, then
10.8 Ton alfalfa*115 acre/1 acre = 1242 Ton alfalfa, for this are required 72 in3, so 72 in3*1 gal / 231 in3 ≅0.31168 gal, if 1242 Ton alfalfa * 2204.62 pound/1 Ton alfalfa = 2738038 pound then 106 pound alfalfa * 0.31168 gal / 2738138 pound ≅ [tex]1.206*10^{-5}[/tex] gallons of water per year
