Answer

8.5 ounces

Explanation

The weight of the paperweight is proportional to its volume. 1 cubic inch weighs 1.8 ounces. To find how many ounces, x, 4.7 cubic inches weigh, we can use the next proportion:


\frac{1\text{ cubic in}}{4.7\text{ cubic in}}=\frac{1.8\text{ ounces}}{x\text{ ounces}}

Solving for x:


\begin{gathered} 1\cdot x=1.8\operatorname{\cdot}4.7 \\ x=8.5\text{ ounces} \end{gathered}
