Question

The density of copper is 8900kg/m3.Find out the density of a sphere made of copper whose mass is 3000kg?​

Answer 1

Answer:

The density of a sphere made of copper is 0.34m3.

Explanation:

Here, let us look at the parameters given:

Density of copper which is 8900kg/m3.

Mass of the sphere, which is made of copper is 3000kg.

They are asking about the density of a sphere which is made of copper, which means it's volume.

The formula of mass as we know is, Mass = Volume×Density

Let us put the values given in the formula;

3000kg= V×8900kg/m3

Therefore,

V= 3000kg/8900kg/m3

  = 30kg/89kg/m3(since the zeroes cancel out)

  = 0.337m3 or 0.34m3

Answer 2

The density of a sphere made of copper whose mass is 3000kg is 8900 kg/m³ and volume= 0.34 m³.

Step by step calculations

Given:

1. Density of copper = 8900kg/m³
2. Mass of copper sphere = 3000kg

Density of copper sphere of mass 3000 kg = 8900 kg/m³.

Formula: Density = Mass/ Volume.

        8900kg/m³ = 3000/ Volume

         Volume = 3000/ 8900 m³

        Volume = 0.337 m³≅ 0.34m³.

The copper sphere of mass 3000 kg having volume of 0.34 m³ have density of 8900 kg/m³.
