Answer:
The weight of the enlarged paperweight is ![1.2\ lb](https://tex.z-dn.net/?f=1.2%5C%20lb)
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes (or its weights) is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x ----> the enlarged paperweight weight
y ----> the original paperweight weight
![z^{3}=\frac{x}{y}](https://tex.z-dn.net/?f=z%5E%7B3%7D%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![z=2](https://tex.z-dn.net/?f=z%3D2)
![y=0.15\ lb](https://tex.z-dn.net/?f=y%3D0.15%5C%20lb)
substitute and solve for x
![2^{3}=\frac{x}{0.15}](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D%5Cfrac%7Bx%7D%7B0.15%7D)
![x=2^{3}(0.15)=1.2\ lb](https://tex.z-dn.net/?f=x%3D2%5E%7B3%7D%280.15%29%3D1.2%5C%20lb)
