Question 72440This question is from textbook For All Practical Purposes
: I asked this question a few days ago and haven't received an answer. I hope to get it answered now.
Doll houses and their furnishings are usually built to scale of exactly 1 in to 1 ft, meaning that an item 1 ft long in a real house is 1 in long in a dollhouse.
a) What is the linear scaling factor for a dollhouse?
b) If a dollhouse were made of the same materials as a real house, how would their weights compare? This question is from textbook For All Practical Purposes

a) The linear scaling factor for the dollhouse = 1inch%2F1foot = 1inch%2F12inch = 1%2F12
b) Mass = Volume x Density

If a dollhouse were made of the same materials as a real house, then density of both houses will be same.
So, the one with larger volume will have larger weight.
Ratio of volume of doll house to original house = %28Scaling_Factor%29%5E3 = %281%2F12%29%5E3 = 1%2F1728
Hence the weight of the doll house is 1%2F1728 times the weight of the real house.
