B: A rectangular block of material that acts as a paperweight is on your dad's desk. The measurements are 3cm. x 4cm. X 6cm, and ithas a mass of 184.32 grams. Determine what the paperweight is made of

Answer :

Answer: Marble.

Explanation

• The, density, is a measure of the ,mass per unit volume ,of a substance, and it is specific of the material. The formula to calculate it is:

[tex]\rho=\frac{m}{V}[/tex]

where ρ represents the density, m the mass, and V the volume.

The first step to get ρ is to calculate V using the dimensions we are given:

[tex]V=3\times4\times6=72cm^3[/tex]

Then, as we are given the mass, we can replace these values in the formula of ρ:

[tex]\rho=\frac{184.32g}{72cm^3}=2.56\frac{g}{cm^3}[/tex]

Then, the density of the material is 2.56g/cm³, which is Marble.
