tolong bantuin dong kak
Penjelasan dengan langkah-langkah:
v = 4.096 cm³
cari dulu panjang sisi rusuk (s)
v = s³
s = ³√4.096
s = 16 cm
s = BC = AB = AE = 16 cm
krmudian cari panjang diagonal bidang (EB)
EB² = AB² + AE²
EB² = 16² + 16²
EB² = 4096 + 4096
EB² = 8.192
EB = √8.292
EB = √4,096 x √2
EB = 16√2
luas bidang BCEH (L)
L = BC x EB
L = 16 x 16√2
L = 256√2
jawabannya : b
