Question

an iron rod of length 25 cm weights 196.5 g. what will be the weight of an iron rod of length 1.6 m?

Answer 1

Answer:

x = 1.2576 kg

Step-by-step explanation:

length ∞ weight (directly proportional)

L1 : L2 : : W1 : W2

25 : 160: : 196.5 : x

25x = 196.5 × 160

x = 196.5 × 160/25

x = 1257.6 g

x = 1.2576 kg

Note : 1.6 m = 160 cm

Answer 2

Answer:

1.2576

Step-by-step explanation:

25x = 196 × 160

X = 196.5 × 160/25

X= 1257.6g

X = 1.2576 kg
