How should I scale Barbie?

• If Barbie were as tall as me, she would be 5 ft 8
  in tall, but her wrist wouldnt be big enough for
  her bones.

• If Barbies wrist were as big as mine, she would
  be 8 ft 8 in tall (but her wrist bones would
  probably be bigger now.)

Change Barbies proportions yourself

How much would Barbie weigh?

• We have made Barbie larger by multiplying by the
  same scaling factor.
• Weight is different it depends on volume, not
  just length.

How much would Barbie weigh?
Here are two cubes. Determine the ratio of their
volumes to find the ratio of their weights.
Small cube 1 in sides
Large cube 4 in sides
Ratio of the sides is 4 to 1 What is the ratio of
the volume of the large cube to the small cube?
64 to 1 64 small cubes make one large cube 64
is 4 cubed
Change volume or weight by multiplying by the
ratio of the lengths cubed
