Question

the mass of an object is 45 kg and it has a density of 5 gram per centimetre cube what is the volume ​

Answer 1

5 grams fits into 45 kg 9,000 times.

Since each 5 grams occupies 1 cm³, 9,000 little packages of 5 grams must occupy 9,000 cm³ . (That's 9 liters.)

Answer 2

Density = Mass/Volume

=> 5g/cm³ = 45kg/Volume

=> 0.005kg/cm³ = 45kg/Volume

=> Volume = (cm³×45kg)/0.005kg

=> Volume = 9000kg/cm³
