Bab Bangun Ruang
Luas permukaan limas :
= Luas alas + 4 (Luas segitiga)
Keliling alas = 4 . s
48 = 4 . s
s = 48 / 4
s = 12 cm
Luas alas :
= s . s
= 12 . 12
= 144 cm²
Tinggi segitiga :
= √tinggi limas² + (1/2 . alas²)
= √8² + (1/2 . 12²)
= √(64 + 36)
= √100
= 10 cm
Luas segitiga :
= 1/2 . s . t
= 1/2 . 12 . 10
= 60 cm²
Luas permukaan limas :
= Luas alas + 4 (Luas segitiga)
= 144 + 4 (60)
= 144 + 240
= 384 cm²
Maaf kalau salah
