Question

a solid block weighs 20 kg its volume is found to be 4000 cm cube find density in g per cm cube and kg per m cube

Answer 1

Answer:

Here is the answer to your question:

Explanation:

Given: Density of the block= 4000 cm³ = 0.004 m³ [Since, 1m³= 10,00,000 cm³

           Weight of the block= 20 kg= 20,000 g  [Since, 1kg = 1000g]

Pressure= Mass/ Volume

= 20000/ 4000= 5 g/cm³

In Kg/m³

= 20/ 0.004 = 5000 Kg/m³.
