Penjelasan dengan langkah-langkah:
BANGUN RUANG DATAR PRISMA
a = 8 cm
Luas = ½ × a × t
t = 2 × 60
8
t = 120
t = 15 cm
s = √(t² + a²) = √(15² + 8²) = √(225 + 64)
s = √289
s = 17 cm
t.p = 30 cm
Luas permukaan Prisma
= a × t + (a + t + s) × tp
= 8 × 15 + (8 + 15 + 17) × 30
= 120 + 40 × 30
= 120 + 1.200
