But everyone knows, by experience, what 3300 individual roughly one pound bags of sugar weighs and what sort of force is needed to hold it up. Mid sized car is ambiguous, and nobody saw anybody hold that up (seeing hulk doesn't count)
I'm a guy who never cooks, I have no incentive to play dumb. I don't buy flour or sugar or other random raw ingredients in bulk. The closest I get is maybe a jar of coffee.
There you go, it looks like a jar with roughly 380 grams of coffee. Since you mention a jar, I assume you mean instant coffee. Your jar will be a bit taller than the packet of sugar with a similar surface area. A pound is a pound. It doesn’t matter if it’s 3300 pounds of feathers, or coffee, or sugar.
