Question

2. An iron block weighs 23.4 kg. Its volume is found to be 3000 cm? Find its density in g/cm' and in kg/m² Ans: 7.8 g/cm3.7800 kg/mᵒl​

Answer 1

Answer:

since density is simply Mass÷Volume

Mass=23.4 kg=23400g

since 1000 Cm³=1 litre

3000 cm³=3 L

Density =23.4÷3×10³

now density is =7.8 g/cm³=7800 kg/m⁰
