8-1-2 Basic Programming Steps Example 1 To calculate the surface area (cm2) and volume (cm3) 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. The following are the formulas used for calculating surface area S and volume V of a regular octahedron for which the length of one side A is known. 2 A S = 2 3 A2, V = ---- A3 3 Procedure 1 m PRGM 2 3(NEW)OCTAw*1 3 !J(PRGM)4(?)aav(A)6(g)5(:)*2 c*!x( )d*av(A)x6(g)5(^) !x( )c/d*av(A)Md JJ 4 1(EXE) or w hw(Value of A) w S when A = 7 V when A = 7 w wbaw w S when A = 10 V when A = 10 w wbfw w*3 S when A = 15 V when A = 15 *1Press 3(NEW) and the cursor changes form to indicate alpha character input. *2The following shows how the calculation of the surface area and volume of a regular octahedron would be calculated using a manual calculation.
