Answer: The length of the rectangular prism is 2 inches long

Explanation:

The volume of a rectangular prims is its height multiplied by its width multiplied by its length

h×w×l=70

We can sub in the known values of width and height and simplify

5×7×l=70

35l=70

Finally, divide both sides by 35 to isolate l


(35l)/(35) =(70)/(35) \\l=2
