luas alas prisma = 1/2 x alas x tinggi
= 1/2 x 16 cm x 17 cm
= 136 cm^2
luas 1 segitiga sisi = 1/2 x alas x tinggi
= 1/2 x 16 cm x 12 cm
= 96 cm^2
luas permukaan prisma = 2 x luas segitiga sisi + luas alas
= 2 x 96 cm^2 + 136 cm^2
= 328 cm^2
luas permukaan prisma = [tex]\color{aqua} {\bf 328 ~cm^2}[/tex]
