volume prisma segitiga :
v = ((alas × tinggi) ÷ 2) × tinggi prisma
v =(( 10 cm × 12 cm) ÷ 2) × 21 cm
v = 120 cm ÷ 2 × 21 cm
v = 60 × 21 cm
v = 1,260 cm
Luas permukaan prisma segitiga :
L = (2 × luas alas) + (keliling × tinggi prisma)
L = (2 × 10 cm) + (12 cm × 21 cm)
L = 20 cm + 252 cm
L = 272 cm

y -y1 = m(x - x1)
y - 5 = 2 . (x - 8)
4(y - 5) = 2x + 24
3x + 4y = 24 + 20
3x + 4y = 44
