Answer: 95 cm³
Explanation: To find the volume of any prism, you have to multiply the base × width × height.
In this case, this 3D shape is split into 2 parts.
The first part's dimensions are 8×5×2. So the volume is 80 cm³.
The second part's dimensions are 1×3×5. So the volume is 15 cm³.
Finally, you add both volumes together, and the final answer is 95 cm³.
