V = p x l x t
= 10 x 8 x 15
= 1.200 cm3
Lp = 2 x (p.l + l.t + p.t)
= 2 x (10.8 + 8.15 + 10.15)
= 2 x (80 + 120 + 150)
= 2 x 350
= 700 cm
Luas Permukaan = 2 × (pl + pt + lt)
= 2 × ((10 cm × 8 cm) +
(10 cm × 15 cm) +
(8 cm × 15 cm))
= 2 × (80 cm² + 150 cm² +
120 cm²)
= 2 × 350 cm²
= 700 cm²
Luas permukaan prisma tersebut adalah 700 cm²
V = p × l × t
= 10 cm × 8 cm × 15 cm
= 80 cm² × 15 cm
= 1.200 cm³
Volume prisma tersebut adalah 1.200 cm³
