Hitunglah luas permukaan gabungan bangun ruang berikut​

Lp. Bangun 1 = 2 × (pl + pt + lt)

= 2 × (18.5 + 18.6 + 5.6)

= 2 × (90 + 108 + 30)

= 456 cm²

Lp. Bangun 2 = 2 × (pl + pt + lt)

= 2 × (12.5 + 12.5 + 5.5)

= 2 × (60 + 60 + 25)

= 290 cm²

Lp. Gabungan

456 + 290

= 746 cm²

semoga membantu
