pnjng kawt = 10 m = 1.000 cm
ukurn balok = 10 x 8 x 6 cm
maka :
Rangka = 4 x (10+8+6)
= 4 x 24
= 96 cm
Untuk membuat 1 rangka tersisa = 1000 - 96 = 904 cm
jika dibuat keseluruhn , dapat dibuat = 1000/96 = 10 rangka
dan tersisa kawat = 1000 - (10x96) = 1000 - 960 = 40 cm
= 4 ( 10 cm + 8 cm + 6 cm )
= 4 ( 24 cm )
= 96 cm
= 0,96 m
Maka, kawat yang tersisa :
10 m : 0,96 m = 10 balok sisa 0,4 m atau 40 cm
