Answer: 128 m³
Step-by-step explanation: In this problem, we're asked to find the volume of the given rectangular prism.
To find the volume of a rectangular prism or a prism whose base is a rectangle, we use the formula shown below.
Volume = length · width · height
Since the rectangular prism has a length of 8 m, a width of 4 m, and a height of 4 m, we can plug this information into the formula to get (8 m)(4 m)(4 m) to get 128 m³.
So the volume of the given rectangular prism is 128 m³.
