To start with, let's compute the volume using this formula:Volume = length x width x height = 9in x 4in x 9in = 144 in
For the second item, use the same formula to get the volume:Volume = length x width x height = 1.89 in x 4in x 9in = 68.04 in
Just take note to indicate your in with an exponent of 3. I just can't type it here so do it when you do your assignment.
