<prompt> Bala sebaka sa bokaholimo ba prism ea octagonal.Prism ea octagonal e nang le lehlakore ka leng ke 3 cm ka bolelele le bolelele ba 5 cm  <response>: Instruction in English: Calculate the surface area of an octagonal prism. . Response in English: Sure, I can help you calculate the surface area of an octagonal prism. First, lets find the area of one of the octagonal faces. Since an octagon can be divided into 8 isosceles triangles with an apothem, we first find the apothem of the octagon using Pythagorean theorem. Knowing that a 3 cm, which is half of the side of one triangle based on the octagonal center: a 32r a2 - a22 2.165 cm rounded to 3 decimal places The area for one triangle is 12bh:Atriangle 32.1652 3.2475So the total area of the octagonal face will be:Aoctagon 8Atriangle 83.2475 25.98Now, lets find the area of the lateral faces of the prism, which are rectangles with a base of 3 cm and height of 5 cm.Arectangle 35 15Since there are 8 rectangles, the total area of the lateral faces is:Alateral faces 815 120Now we can find the total surface area of the octagonal prism by adding the areas of the two octagonal faces and the lateral faces:SA 2Aoctagon Alateral faces SA 2 25.98 120 SA 171.96So, the surface area of an octagonal prism with each side 3 cm in length and a height of 5 cm is approximately 171.96 cm2. . Response in Sesotho: Ehlile, nka u thusa ho bala sebaka se kaholimo sa prism ea octagonal. Pele, a re fumaneng sebaka sa sefahleho se seng sa octagonal. Kaha octagon e ka aroloa ka li-triangles tse 8 tsa isosceles ka apothem, re qala ka ho fumana apothem ea octagon ho sebelisa theorem ea Pythagorean. Ho tseba hore a 3 cm, e leng halofo ea lehlakore la khutlotharo e le ngoe e thehiloeng bohareng ba octagonal: a 32 r a2 - a22 2.165 cm e chitja. ho ea ho libaka tse 3 tsa decimal Sebaka sa khutlotharo e le ngoe ke 12bh: Atriangle 32.1652 3.2475 Kahoo kakaretso ea sefahleho sa octagonal e tla ba: Aoctagon 8 Atriangle 83.2475 25.98 Joale, a re fumaneng sebaka sa lifahleho tsa lateral tsa prism, e leng li-rectangles tse nang le motheo oa 3 cm le bolelele ba 5 cm. Arectangle 35 15 Kaha ho na le khutlonnetsepa tse 8, sebaka sohle sa lifahleho tse ka thoko ke: Alateral faces 815 120 Joale re ka fumana kakaretso ea sebaka sa prism ea octagonal ka ho eketsa. libaka tsa lifahleho tse peli tsa octagonal le lifahleho tsa lateral: SA 2 Aoctagon Alateral faces SA 2 25.98 120 SA 171.96 Kahoo, sebaka se ka holimo sa prism ea octagonal ka lehlakoreng le leng le le leng 3 cm. ka bolelele le bolelele ba 5 cm ke hoo e ka bang 171.96 cm2.
