To find the number of 1/8 inch cubes needed to completely fill the rectangular prism, we need to find the volume of the rectangular prism in terms of 1/8 inch cubes.
To do this, we can convert the volume from the mixed number format to an improper fraction.
1 5/16 = (1 * 16 + 5)/16 = 21/16
Now, we can multiply this fraction by the number of 1/8 inch cubes that fit in the rectangular prism to find the total number of cubes needed.
The volume of the rectangular prism is 21/16.
Since each cube has a volume of 1/8 inch, we can set up the following equation:
(21/16) / (1/8) = (21/16) * (8/1) = 168/16 = 10.5
Therefore, 10.5 or 10 1/2 cubes are needed to completely fill the rectangular prism.
