Kelas 8 MatematikaBab Bangun Ruang
s = √((d1 : 2)² + (d2 : 2)²)
s = √((12 : 2)² + (16 : 2)²)
s = √(36 + 64)
s = √100
s = 10 cm
Luas prisma
= (2 . 1/2 . d1 . d2) + (4 . s . tinggi prisma)
= (12 . 16) + (4 . 10 . 20)
= 192 + 800
= 992 cm²
= √ 6² + 8²
= √ 36 + 64
= √ 100
= 10 cm
Luas permukaan prisma
= 2 × La + K. Alas × t
= 2 × ( ½ × 12 × 16 ) + ( 4 × 10 ) × 20
= 2 × 96 + 40 × 20
= 192 + 800
= 992 cm²
