The length of the space in the rectangular prism is 4 units.
Wrong
Apologies for the mistake. To find the length of the space in a rectangular prism, you simply need to look at the side length that represents the space within the prism. In this case, the length of the space would be the dimension that corresponds to the "length" of the rectangular prism. Therefore, the length of the space in this rectangular prism is 4 units.
