Answer:
416 mm^3
Explanation:
The equation for the volume of a rectangular prism is
![Volume = Length * Width * Height](https://img.qammunity.org/2023/formulas/mathematics/middle-school/pt7q6z71d693qu9r4wk1wg0agjidvyq50a.png)
We will use Length = 5 mm, Width = 10.4 mm, and Height = 8 mm
![V = 5mm * 10.4mm * 8mm\\\\=416 mm^3](https://img.qammunity.org/2023/formulas/mathematics/middle-school/hbcic5gs80xkk3l5uc5l7bv1g7yxy4nofr.png)
Important things to note:
- The unit in the final answer is mm^3 because when you multiply "like terms" together, their exponents are added together
![a^b*a^c*a^d\\\\= a^b^+^c^+^d](https://img.qammunity.org/2023/formulas/mathematics/middle-school/y09pkitwwzqicn1uzeftz790rm0alb9eaf.png)
