= 100 cm
s = 5 cm
t = 6 cm
Rusuk = 2(Ka) + Jumlah p rusuk tegak
= 2(3 × s) + (3 × t)
= 2(3 × 5) + (3 × 6)
= 2(15) + 18
= 30 + 18
= 48 cm
Sisa = Kawat : Rusuk
= 100 cm : 48 cm
= 2 sisa4 cm
Jadi sisa kawat yang tidak terpakai adalah 4 cm.
= (2 x 3 x 5) + (3 x 6)
= 30 + 18
= 48 cm
banyak kerangka yang bisa dibuat adalah
= 100 : 48
= 2 sisa 4 cm
sisa kawat = 100 - (2x48) = 4 cm
