= 9² + 12²
= 81 + 144
= 225
= √225 = 15 cm
Lperm = 2xluas alas + luas selimut
= 2x1/2x18x24 + 4x10x15
= 432 + 600
= 1032 cm²
kliling = 4 x s
= 4 x 15
= 60
La = D₁ x D₂ : 2
= 18 x 24 :2
= 18 x 12
= 216 cm²
luas permukaan
Lp = 2 x La + k x t
= 2 x 216 + 60 x 10
= 432 + 600
= 1032 cm²
jawabannya 1032 cm²
