Answer:
The width is 9 cm
Explanation:
Since the formula for the volume of a rectangular prism is,
Volume = (Height)(Length)(Width)
So,
Width = (Volume)/((Height)(Length))
Now, Volume = 2691, Height = 23, Length = 13, so, we get for the width,
Width = (2691)/((23)(13))
Width = 117/13
Width = 9
So the width is 9 cm
