If H is the height, then the length of the box is (80 – 2H) and the width is (40 –
2H). The volume V is:

It seems reasonable that either a tall, narrow box or a short, flat box could be
formed having the desired volume. Because the taller box is preferred, larger
initial estimates of the height are reasonable. However, heights greater than
20 cm are not physically possible because the metal sheet is only 40 cm wide.
Initial estimates of 10 and 20 cm are therefore appropriate.

Questions and answers
how to change the mode on the calculator because when I do simple addition it doesn't work.
The HP 32SII calculator adds numbers in the X- and Y-registers and displays the result as a fraction. To switch to the current decimal display format, refer to chapter 5, "Fractions." If needed, press the appropriate mode key to switch between fraction and decimal modes.
