Luas Permukaan Prisma
2 × ( ½ × a × t ) ( a + s + t ) × tinggi prisma
2 × ( ½ × 20 × 15 ) ( 20 + 21 + 15 ) × 8
2 × ( 10 × 15 ) ( 56 ) × 8
2 × 150 ( 56 ) × 8
300 ( 56 ) × 8
16.800 × 8
134.400 cm²
Luas Alas = 20 × 21 = 420
Tinggi Prisma = 8 cm
Tinggi = 15 cm
= 2(luas alas.A.t)(a.s.t) × t
= 2(1/2.20.15)(20 + 21 + 15) × 8
= 2.150.56.8
= 16800.8
= 134400 cm³

Diketahui
Luas Alas = 20 × 21 = 420
Tinggi Prisma = 8 cm
Tinggi = 15 cm
Ditanya
= 2(luas alas.A.t)(a.s.t) × t
= 2(1/2.20.15)(20 + 21 + 15) × 8
= 2.150.56.8
