Question

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 1

Answer: Marble.

Step-by-step 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:

`\rho=(m)/(V)`

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:

`V=3*4*6=72cm^3`

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

`\rho=(184.32g)/(72cm^3)=2.56(g)/(cm^3)`

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