Jawaban:
B. 4.104 cm²
Penjelasan dengan langkah-langkah:
Diket :
AB=BC=AC=DE=EF=DF = 24 cm
TC = 9 cm
AD = 54 cm (t)
Dit : Luas permukaan?
Lp = 2 × L.alas + K.alas × t
Lp = 2 × (1/2 × AB × TC) + (AB + BC + AC) × AD
= 2 × (1/2 × 24 × 9) + (24 + 24 + 24) × 54
= 2 × 108 + 72 × 54
= 216 + 3.888
= 4.104 cm²
Jadi, jawabannya adalah 4.104 cm².
