Jawaban:
c.1.980 cm²
Penjelasan dengan langkah-langkah:
menggunakan rumus phytagoras
c² = a² + b²
c² = 5² = 12²
c² = 25 + 144
c² = 169
c = √169
c = 13 cm
Luas selimut = (a + b + c) × tinggi prisma
= (5 + 12 + 13) cm × 22 cm
= 30 × 22 cm²
= 660 cm²
Luas karton = banyak papan nama × luas selimut
= 3 × 660 cm²
= 1980 cm²
semoga membantu :3
