If there are two identical pyramids except one is twice as large as the other (i.e. all linear dimension are twice those of the other pyramid), how much does more the larger one weigh? Assume they are both solid and made of the same stone. [hint: weight is proportional to volume.]
_______________________________________times as much
I've tried this problem a few time without getting it correct, since the pyramid is twice as large, doesn't that mean that the volume would increase by a factor of 4?
