C. 10 units
Explanation:
The formula for the volume of a rectangular prism is length x width x height.
Lets multiply the length and height:
Multiply 24 x 5= 120
If the volume of the rectangular prism is 1,200 cubic units, we need to multiply some number to 120 so we can get the volume 1,200 cubic units.
Divide 1,200 by 120
Its 10 units.
