Example 1 To calculate the surface area (cm
2
) and volume (cm
3
) of three regular
octahedrons when the length of one side is 7, 10, and 15 cm,
respectively.
Store the calculation formula under the file name OCTA.

Pressing w while the final result of a program
is on the display changes to the program list.
#You can also run a program while in the RUN
•
MAT Mode by inputting: Prog ”<file name>” w.
# Pressing w while the final result of a program
executed using this method is on the display
re-executes the program.
#An error occurs if the program specified by Prog
”<file name>” cannot be found.
