Using an Existing Program to Create a New Program
Sometimes you can input a new program by using a program already in memory as a base.
Simply recall the existing program, make the changes you need, and then execute it.

Example 2
To use the OCTA program (page 8-1-2) to create a program that
calculates the surface area (cm
2
) and volume (cm
3
) of regular
tetrahedrons when the length of one side is 7, 10, and 15 cm
Use TETRA as the file name.
The following are the formulas used for calculating surface area S
and volume V of a regular tetrahedron for which the length of one
side A is known.
Use the following key operations when inputting the program.

Compare this with the program for calculating the surface area and volume of a regular
octahedron.

the OCTA program.
