The volume of the material that must be used to make a star with the mass of the sun is 1.2×10⁵¹ m³.

### What is volume?

Volume is the amount of space occupied by an object or a plane figure.

To calculate the volume of the material that must be used to make a star with the mass of the sun, we use the formula below.

Formula:

• D = m/V............ Equation 1

Where:

• D = Density of the interstellar gas
• m = mass of the sun
• V = Volume of the material

Make V the subject of the equation

• V = m/D........... Equation 2

From the question,

Given:

• m = mass of the sun = 1.9891×10³⁰ kg
• D = 1 atom/cm³ = 1.66×10⁻²¹ kg/m³

Substitute these values into equation 2

• V = ( 1.9891×10³⁰)/(1.66×10⁻²¹)
• V = 1.2×10⁵¹ m³

Hence, The volume of the material that must be used to make a star with the mass of the sun is 1.2×10⁵¹ m³.
