Answer 2

It seems like you're trying to perform a mathematical operation involving some numbers, but the expression you provided is a bit unclear. "252т" appears to be a value, but I'm not sure what unit it represents. Similarly, "400кг" seems to be 400 kilograms. If you could provide more context or clarify the units, I'd be happy to help you with the calculation.
