We can see from the table that the maximum value of volume occurs when the height
Hence, the sides will be
d.
Compare your result with that of part (c).
d.

Answer to Problem 93E
The results of the both parts match.
Explanation of Solution
Calculation:
Let us draw the graph of the function
So, from the graph we can observe that the maximum volume is at the height of
Hence, the results of the both parts match.
