please helpppp :)) thank you!

Answer: 216 [tex]m^3[/tex]
Step-by-step explanation:
Hello! In order to find the total volume, you need to find the volume of the two rectangular prisms. Make sure to cross a line into how you will define them (check the picture to see how I defined it).
To find the volume of the first rectangular prism, multiply the three dimensions.
[tex]8*5*3 = 120 m^3[/tex]
Now, the second rectangular prism gives you:
[tex]6*2*8 = 96m^3[/tex]
Add the volumes of the two rectangular prisms:
[tex]120 + 96 = 216 m^3[/tex]
