Step-by-step explanation:
Answer:
486kg
Step-by-step explanation:
density = mass / volume
2.7 = m / (100 x 60 x 30) **** Note the conversion to cm as the density is given in g/cm.
2.7 = m / 180000
m = 486000g
Now convert to mass in kg:
486000 g x 1 kg / 1000 g = 486kg
The six is in the hundredths place so we will out the fraction as “over a hundred”, meaning 16/100. But this can be simplified to 4/25 :)
So 4/25 is your answer
