Answer:
[tex]420 \: {mm}^{3} [/tex]
Step-by-step explanation:
The formula to find the volume of a rectangular prism is
[tex]volume \: = length \times \: width \times height[/tex]
The length of this shape is 5mm, the width is 10.4mm, and the height is 8mm. Therefore the volume is
[tex]5 \times 10.5 \times 8 = 420 {mm}^{3} [/tex]
