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? Ratio of the sides is 4 to 1 What is the ratio of the volume of the large cube to the small cube? Small cube 1 in sides Large cube 4 in sides 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 Here are two cubes. Determine the ratio of their volumes to find the ratio of their weights.
