Question

find the volume of an object whose density is 40kg /m³ and it's mass is 4120 kg ​

Answer 1

1 kg = 1000 g

1 L = 1000 mL = 1000 cm^3

so 1.60 g/cm^3 is also = 1.60 kg /L because you are multiplying and also dividing by 1000 for conversions.

Since density = mass/volume, then volume = mass/density
