Tolong no 34 di bantu please

LPp∆ = 2alas + s1 + s2 + s3

•alas = a × t(alas) / 2
=> alas = 6×8/2
=> alas = 24 cm²

•s1 = p1 × t(prisma)
=> s1 = 6 × 9 = 54 cm²

•s2 = p2 × t(prisma)
=> s2 = 8 × 9 = 72 cm²

•s3 = p3 × t(prisma)
=> s3 = 10 × 9 = 90 cm²

LPp∆ = (2×24) + 54 + 72 + 90
=> LPp∆ = 48 + 216
=> LPp∆ = 264 cm²
