luas permukaan prisma
= 2 x p alas x l alas + 2 x (p alas + l alas) x t prisma
= 2 x 10 x 7 + 2 x (10 + 7) x 25
= 2 x 70 + 2 x 17 x 25
= 140 + 34 x 25
= 140 + 850
= 990 cm²
semoga membantu jangan lupa untuk follow ya
p = 10 cm
l = 7 cm
t = 25 cm
Lp = 2 × (p × l + p × t + l × t)
Lp = 2 × (10 × 7 + 10 × 25 + 7 × 25)
Lp = 2 × (70 + 250 + 175)
Lp = 2 × 495
Lp = 990 cm^2
