To find the density:

⇒ must find the relationship between the density, mass, and volume

⇒ $Density = \frac{mass}{volume}$

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

$Volume = 8cm * 5cm * 5cm = 200cm^3$

LEt's calculate the density now:

$Density = \frac{1890g}{200cm^3} =9.45g/cm^3$

Answer: The density of the copper is 9.45g/cm^3 or Choice (A)

Hope that helps!
