panjang seluruh sisi kerangka balok = 4(P + L + T)
= 4(10 + 8 + 6)
= 4(24)
= 96 cm
sisa kawat = 500 - 96 = 404 cm
Kalau misalnya ditanyanya banyak balok yang bisa dibuat dan sisanya :
500 / 96 = 5 20/96
= 5 balok dengan sisa 20 cm
= 4×10+4×8+4×6
= 40+32+24
= 96 cm
5 m = 500cm
sisa kawat = 500 cm - 96 cm = 404 cm
maaf kalau salah ....
