tolong dijawab iya pake caranya hitung lah luas dari masing prisma

C. L = 2 × La + (Ka × T)

= 2 × (1/2×A×T) + (S×S×S × 35)

= 2 × (1/2×18×12) + (18×18×18 × 35)

= 2 × (1×9×12) + (5.832×35)

= 2 × 108 + 204.120

= 216 + 204.120

= 204.336 cm^2



D. L = 2 × (p×l + p×t + l×t)

= 2 × (8×6 + 8×15 + 6×15)

= 2 × (48 + 120 + 90)

= 2 × 258

= 516 cm^2
