How Long Could An Adult And Infant Survive On Baby Formula, If Necessary? (in A Doomsday Type Scenario)?

My baby girl just turned one year old and I realized I have a bunch of cans of formula left over. Last night, as I was re-packing our “emergency readiness kit” I was wondering if, in a emergency situation, the formula would technically be sufficient to keep an adult and toddler alive and well for several weeks if necessary. Provided I had enough water supply to mix with the powdered formula, how long could it keep us alive and well, assuming we were in a doomsday scenario – hunkered down in my basement? Thanks!
