a.) Luas permukaan prisma = 2 x luas alas + luas selimut
Luas alas = (13 + 7) / 2 x 8 = 84 cm^2
Luas selimut = 2 x luas trapesium siku-siku
Luas trapesium siku-siku = (13 x 8) / 2 = 52 cm^2
Luas selimut = 2 x 52 = 104 cm^2
Luas permukaan prisma = 2 x 84 + 104
= 272 cm²
b.) Volume prisma = luas alas x tinggi
Volume = 84 x 12
= 1008 cm³
