\( 350g \times 2.1Kg = 350g \times 2100g \) (since 1Kg = 1000g)
\( = 735000g^2 \)
However, please note that the units in the final answer do not make physical sense as you usually do not multiply masses directly in that manner to get \( g^2 \). In most physical contexts, such a calculation would likely be incorrect because it violates the principles of dimensional analysis. The concept of "grams squared" is not a standard measure in physics or other sciences involving mass.Email: camtutor.ai@gmail.com
