11-17.

Mia found the volume of a rectangular prism to be $840\text{ mm}^3$. As she was telling her father about it, she remembered that the base had a length of $10$ mm and a width of $12$ mm, but she could not remember the height. “Maybe there’s a way you can find it by going backwards,” her father suggested. Can you help Mia find the height of her prism? Explain your solution.

Volume of a rectangular prism is $\text{(base area)(height)}$.
