Solution:
Given that, 6 identical toys weigh 1.8 kg
we know that, 1kilogram = 1000 grams
6 identical toys weigh in grams
[tex] 1.8 * 1000 =1800 [/tex]
6 identical toys weigh 1800 grams
then calculating the weight of 1 toy by unitary method ,
weight of 1 toy =[tex] \frac{1800}{6} = 300 [/tex] grams.
Hence, 1 toy would weigh 300 grams.
