To find the density:
 ⇒ must find the relationship between the density, mass, and volume
  ⇒ [tex]Density = \frac{mass}{volume}[/tex]
Let's examine the information given:
- weight: 1890g
- dimensions: 8cm * 5cm* 5cm
Let's first find the volume:
  ⇒ the volume is the dimensions multiplied together
   [tex]Volume = 8cm * 5cm * 5cm = 200cm^3[/tex]
LEt's calculate the density now:
 [tex]Density = \frac{1890g}{200cm^3} =9.45g/cm^3[/tex]
Answer: The density of the copper is 9.45g/cm^3 or Choice (A)
Hope that helps!
