The weight of a 170 cm steel bar will be 5 Kg
Step-by-step explanation:
Derek uses a 136 cm flat steel bar that weighs 4 kg to make rack in the garage.
1 kg = 1000 gm
So the weight of 1 cm steel bar will be [tex]\frac{4 }{136}[/tex] kg
Weight of 1 cm bar = [tex]\frac{4000}{136}[/tex] gm
Let the weight of a 170 cm steel bar will be [tex]\frac{4000 }{136}[/tex] × [tex]170[/tex] gm
⇒[tex]4000[/tex] × [tex]1.25[/tex] gm
⇒ 5000 gm
⇒5 kg
Hence, the weight of a 170 cm steel bar will be 5 Kg
