Question

Lakshya says that,"The Newton's formula of weight f=mg is wrong or right as comparing 100 kg cotton and 100 kg iron both weight are not same,one is heavier than other which means one's weight is more than other.so area is needed to solve this question.hence the formula should be F=m×g+a²; a stands for area.hence Newton's law is wrong?" can you justify?​
