If you can afford a shipping container you can afford a greater amount of building material for the same price, your complete lack of construction ability doesn't make them a better option.
Standard shipping containers are either 20 or 40 by 8 exterior dimensions. So if you have exactly zero modifications or internal walls, so zero hvac electrical or plumbing and one open space you have about 200sq ft if it's on level ground which this isn't.
Your right it's actually higher than that as other people have cited. You literally responded to that comment describing the sun shining on them as "in certain conditions"
I've never seen a house built out of pallets collapse. It's almost like anecdotal evidence isn't worth a shit. The stated life expectancy from manufactures is 20 years if properly maintained and unmodified.

Thank you for being rhe best possible example of how this seems like a good idea if you're a complete fucking moron with zero construction experience, knowledge or ability.
